Nobody sets out to be an accidental landlord. You get a job offer two states away, you move in with a partner, you inherit a parent’s house, or you buy a bigger place and the old one would sell at a loss. Suddenly you own a property you do not live in, and renting it out looks smarter than selling. Roughly a third of small landlords in the United States got started exactly this way. The good news is that your former home can be a solid rental. The bad news is that the habits that made you a good homeowner will not make you a good landlord, and the first 90 days are where most of the avoidable mistakes happen. This guide walks through the decisions in the order you actually need to make them.

First, Decide Whether Renting Beats Selling

Sentiment is a terrible reason to keep a house. Run the numbers before you do anything else. You need three figures: what the house would net if sold today, what it would rent for, and what it costs to carry each month.

  • Net sale proceeds — estimated sale price minus roughly 7 to 9 percent for agent commissions, closing costs, and repairs buyers demand, minus your remaining mortgage balance. That is the cash you are choosing to leave in the house.
  • Realistic rent — pull 5 to 8 comparable listings within a mile that have rented in the last 90 days. Ignore asking prices on stale listings. Use the median, not the top.
  • True monthly carry — mortgage principal and interest, property taxes, landlord insurance (not your current homeowner policy), HOA dues, and a reserve for vacancy and repairs. A conservative rule is 8 percent of rent for vacancy and another 10 percent for maintenance on a house older than 15 years.

If rent minus true carry is positive by at least $150 to $200 a month, you have a workable rental. If it is negative, you are speculating on appreciation, which can be a legitimate choice but should be a deliberate one. There is also a tax wrinkle worth knowing: if you lived in the house for two of the last five years, you can exclude up to $250,000 of gain ($500,000 if married filing jointly) when you sell. Rent it out for more than three years and that exclusion disappears. If the house has appreciated significantly, the clock matters.

Treat the equity sitting in your old house as cash you are choosing to invest in a rental. If you would not buy this exact property as an investment with that cash today, think hard about why you are keeping it.

Read Your Mortgage Before You List It

Almost every owner-occupied mortgage includes an occupancy clause requiring you to live in the home as your primary residence for a set period, usually 12 months after closing. If you have been there longer than that, you are generally free to rent it out without refinancing. If you are inside that window, call your servicer and ask about an exception; job relocation and family changes are commonly approved reasons, but get the approval in writing.

Three other lender issues trip up new landlords:

  1. FHA and VA loans — both allow you to rent the home after meeting the occupancy requirement, but if you want another FHA or VA loan for your next house, your remaining entitlement and debt-to-income ratio get complicated. Talk to a loan officer before you sign a lease.
  2. Escrow and tax reassessment — in some states, converting to a rental removes a homestead exemption, and your property tax bill can jump 15 to 30 percent the following year. Your escrow payment will follow. Budget for it.
  3. Rental income for your next mortgage — most lenders will count 75 percent of a signed lease toward your qualifying income, but only once you have a lease in hand and often only after rent has hit your bank account. Sequence your move accordingly.

Switch Your Insurance the Day the Tenant Moves In

This is the single most expensive mistake accidental landlords make, and it is invisible until something burns. Your standard homeowner policy (an HO-3) assumes you live there. Most insurers will deny a claim, or cancel the policy outright, if they discover a tenant was in place at the time of loss. You need a landlord policy, commonly called a DP-3 or dwelling fire policy.

A DP-3 typically costs 15 to 25 percent more than your homeowner policy, and it covers the structure, your liability as owner, and often loss of rental income if the house becomes uninhabitable after a covered event. It does not cover the tenant’s belongings, which is why you should require renters insurance in the lease, with a minimum of $100,000 in liability coverage and your name listed as an interested party so you are notified if it lapses. Ask your agent about an umbrella policy as well. A $1 million umbrella usually runs $200 to $400 a year and sits on top of both your auto and landlord coverage.

If the house will sit vacant between your move-out and the tenant’s move-in for more than 30 days, tell your insurer. Many policies have vacancy exclusions that kick in at 30 or 60 days, and a burst pipe in an empty house is exactly the claim they will deny.

Get the Tax Setup Right From Day One

Converting a home to a rental triggers a specific tax event that most people handle wrong. On the date the property becomes available for rent, you establish its depreciable basis. That basis is the lower of your adjusted cost (purchase price plus improvements, minus the land value) or the fair market value on the conversion date. Write that number down, along with how you arrived at it. You will depreciate the building portion over 27.5 years, which for a $300,000 structure means roughly $10,900 a year in deductions you did not have as a homeowner.

From that same day, you need to track every dollar in and out of the property. That means:

  • A separate bank account — open a dedicated checking account for rent deposits and property expenses. Commingling with personal money makes your Schedule E a nightmare and weakens your position if a tenant ever disputes a deposit.
  • A record of pre-rental repairs — work done to get the house ready before it is listed is generally added to basis, not deducted. Work done after it is available for rent is usually deductible. The date matters, so keep receipts and photos with timestamps.
  • Mileage and supplies — trips to the hardware store, the property, and the bank are deductible at the standard mileage rate. Most accidental landlords forget this entirely in year one.

You do not need accounting software with a monthly fee for one property. A purpose-built landlord app like KeyLoft lets you log rent, expenses, and receipts per unit as they happen, and it works offline, which matters when you are standing in a basement with no signal photographing a water heater receipt. If you also do contract or freelance work alongside your W-2 job, keep that income entirely separate; tools like Stintly are built for tracking self-employment income and time, and mixing it with rental records only confuses your accountant.

Prepare the House Like a Landlord, Not a Homeowner

You know every quirk of this house: the sticky back door, the outlet that only works when the switch is up, the furnace filter that is a weird size. Your tenant knows none of it, and a house full of “you just have to jiggle it” items generates maintenance calls and resentment. Walk through the property with the mindset of a stranger who is paying you $2,000 a month.

  • Fix every known defect before listing — a $90 outlet repair now prevents a $200 emergency electrician visit and a frustrated tenant later.
  • Remove everything personal and most of what is optional — the garage shelving, the extra fridge in the basement, the hot tub. Anything you leave becomes something you are responsible for maintaining.
  • Re-key the locks — you have handed out keys to neighbors, cleaners, and relatives over the years. A locksmith re-key runs $100 to $200 and is non-negotiable.
  • Replace, do not refinish, where it makes sense — durable, neutral, and cleanable beats beautiful. Luxury vinyl plank over the worn carpet will outlast three tenancies.
  • Check safety items against local code — smoke detectors in every bedroom, carbon monoxide detectors on each level, GFCI outlets in wet areas, and handrails on any stairs with four or more risers. Many cities require a rental inspection before a certificate of occupancy is issued, so call your municipality.

If the make-ready turns into a real project, with a new roof, a bathroom gut, or a kitchen refresh, scope it formally. Get three bids, put the scope in writing, and track change orders. Owners who hire a general contractor sometimes ask what software the contractor uses to manage the job; tools like TrestleBook handle contractor-side job costing and billing, and if your contractor is organized on their end, your invoices will be clean and your records easier to keep.

Every item you leave behind for convenience is an item you have agreed to repair. If you would not want to drive over on a Saturday to fix it, take it out of the house.

Build the Systems Before the First Tenant

The structural difference between a homeowner and a landlord is paperwork. You are entering a legal relationship governed by your state’s landlord-tenant statute, and the tenant has rights that you must know even if you are a nice person who would never violate them. Before you place an ad:

  1. Read your state’s landlord-tenant law summary — most state attorney general websites publish a plain-English guide. Pay attention to security deposit limits and return deadlines, required disclosures (lead paint for pre-1978 homes, mold, flood zones), and notice periods for entry.
  2. Use a state-specific lease — not a generic PDF from a search result. Your state bar or apartment association usually sells one for $30 to $50, and it will include the required disclosures.
  3. Write your screening criteria down before you meet anyone — minimum income (typically 3 times rent), credit threshold, no evictions in the last 5 years, verifiable rental history. Apply the same criteria to every applicant. This is your fair housing protection as much as your financial one.
  4. Decide how rent gets paid — electronic transfer to your dedicated account, due on the first, with a written late fee policy that complies with your state cap. No cash, no “just Venmo me when you can.”
  5. Document the move-in condition — a dated photo set of every room, every appliance, and every existing scuff, signed by both parties. This is the record that settles deposit disputes 12 months later. Keeping those photos attached to the unit record in something like KeyLoft means you can find them in 30 seconds instead of scrolling through a year of camera roll.

The Mindset Shift Nobody Warns You About

The hardest part of renting out a former home is not the paperwork. It is that the house is no longer yours in the way it used to be. The tenant will hang pictures where you would not. They will not mow the lawn on your schedule. They might paint the kids’ room a color you hate. None of that is your business as long as the lease is followed and the property is returned in the same condition minus normal wear.

Three habits protect both the relationship and your sanity:

  • Do not drop by — you no longer have the right to walk in. Most states require 24 to 48 hours written notice for non-emergency entry. Schedule a mid-lease inspection at 6 months, give proper notice, and otherwise stay away.
  • Respond to maintenance like a business — acknowledge within 24 hours, fix non-urgent items within 7 to 14 days, and treat anything involving water, heat, or electricity as urgent. A tenant who sees you respond quickly in month one is a tenant who renews in month twelve.
  • Price for the market, not for your mortgage — your payment is irrelevant to what the house rents for. If comparable homes rent for $1,900 and you need $2,100 to break even, you have a math problem, not a pricing strategy.
The day the tenant moves in, the house stops being your home and becomes your business. The landlords who struggle are the ones who never fully make that switch.

Becoming a landlord by accident does not mean you have to run the property by accident. Make the rent-versus-sell decision on numbers, clear the mortgage and insurance hurdles before anyone moves in, set your depreciable basis and start tracking from day one, prepare the house for a stranger rather than for yourself, and build the lease and screening systems before you take a single call. Do that in the first 90 days and your former home becomes what it should be: a quietly appreciating asset that pays its own way, managed by someone who knows exactly what they are doing.
