Rental property course · Lesson 3 of 6

Rent grows, but the payment does not.

Year 1 shows little about a rental. The rent and the costs grow each year, but the payment on a fixed loan stays the same. This lesson follows Example House for ten years.

EDUCATION, NOT ADVICE · The example property. Example House is a made-up rental. A model script calculates every figure, so you can check each one. The tax figures use 2026 federal rules for a married couple with a joint return, and they leave out state tax. Talk to a tax professional before you act. Full disclosures →

The rent and the costs both grow 3% a year. The payment stays at $17,963. So the cash flow improves each year, and it is positive from year 3.

Three parts of the return

  • Cash flow. Over ten years, Example House gives $19,510 of cash before tax.
  • Principal. Each payment repays part of the loan. Over ten years, the loan falls by $31,922.
  • Growth in value. At 3% a year, the house is worth $403,175 after ten years.

After ten years, the value less the loan is $210,097 of equity. The owner put in $81,000. Lesson 5 shows how much of that equity remains after the costs and taxes of a sale.

What the table leaves out

The model spreads repairs evenly over the years. A real property has years with a new roof or a long vacancy. Keep a cash reserve for these years, so that one large bill does not force a sale.

The model also assumes that rent grows 3% each year. In some years and some towns, it does not. Test a lower figure before you buy.

Key points

  • With a fixed-rate loan, the payment stays the same while the rent grows.
  • The return has three parts: cash flow, principal repaid and growth in value.
  • Keep a reserve for the large repairs that a model spreads evenly.
