New home. New landlord. Now what?

By Mogul Books Team•2026-11-01•3 min read

You bought another home and decided to keep the old one as a rental.

You know the property. You know its mortgage payment and which appliance might need replacing next. What’s new is managing it as an investment—and preparing for the bookkeeping and tax reporting that come with rental income.

Separate the rental from your household spending

Consider a dedicated rental bank account and a separate credit card for property expenses.

Move rental-related payments over deliberately. Keep track of bills still paid from a personal account, and avoid putting expenses for your new home on the rental card.

This separation helps you see what the rental actually costs without sorting through groceries, personal subscriptions, and purchases for two different homes.

Document the transition

Gather your original purchase documents, improvement records, mortgage statements, and receipts for work done as you prepare for tenants.

Record when you moved out and when the property was ready and available to rent. Those dates can differ from the date a tenant moves in.

Keep a clear timeline so your accountant can distinguish personal use from rental activity.

Establish depreciation records at the start

Converting a former home introduces a specific depreciation question. The depreciation basis generally uses the lower of adjusted basis or fair market value at conversion, excluding land. Depreciation generally begins when the property is ready and available for rent. IRS Publication 527

Preserve the purchase history, improvement records, and valuation support your accountant needs. Keep the resulting depreciation schedule with the property’s permanent records.

Getting that starting point documented helps you maintain continuity in later years.

Don’t treat every project the same

Preparing a home for tenants can involve cleaning, repairs, replacements, and larger improvements.

Keep itemized invoices and explain what each project involved. Different costs may require different tax treatment; a rental-related payment isn’t automatically an immediate deduction. IRS Publication 527

Good documentation helps your accountant evaluate eligible expenses and identify costs that need ongoing asset tracking.

Plan for the first return with rental activity

Your tax preparation now needs to account for the rental. Many individual landlords generally report rental income and expenses on Schedule E, although the applicable forms depend on the circumstances. IRS rental reporting guidance

Keep rent, deposits, expenses, and owner contributions clearly identified. Give your preparer organized records and the transition timeline rather than asking them to reconstruct the year.

See the home as an investment

Rent minus the mortgage payment is only a starting point. Track maintenance, insurance, taxes, management, and other costs to understand the property’s performance.

Mogul Books helps organize that activity around the rental, giving your former home a clear place in your financial records.
