Rent-to-Own vs Buy Calculator

1. Enter the years until you buy, home value today, expected appreciation, option fee (upfront) and option fee credited toward price? and the remaining inputs.
2. Optionally add monthly rent credit, closing costs (buy now), property tax rate and homeowners insurance — leave blank to skip.
3. Read the highlighted result first, then the breakdown below it. Load the worked example to check the math by hand.

Both paths are measured at the same moment — the end of the option period — using the same projected home value. Cash spent is everything paid out; equity is the home's value minus what is still owed. Their difference is each path's net position.

• Projected value = home value × (1 + appreciation)^years
• Rent-to-own cash = option fee + rent × months
• Credits = rent credit × months (+ option fee if credited)
• Rent-to-own equity = projected value − (agreed price − credits)
• Buy-now cash = down + closing + (P&I + tax + insurance + maintenance) × months
• Buy-now equity = projected value − remaining mortgage balance
• Net position = equity − cash spent; advantage = buy-now net − rent-to-own net

Net position is what each path leaves you with at the end of the option period — equity minus everything you paid. The higher (less negative) number is the better financial outcome under your assumptions, but rent-to-own still depends on qualifying for a mortgage at exercise.

Common mistakes and assumptions

• Assuming appreciation will be high. Test 0% and a price drop.
• Forgetting that the option fee and credits are usually lost if you don't buy.
• Comparing monthly payments only, ignoring equity built by buying.
• Not confirming in the contract who pays for repairs and property tax.

A $300,000 home, 3 years, 3% appreciation. Rent-to-own: $9,000 credited option fee, $2,100 rent with $300 credit, $320,000 purchase price. Buy now: 10% down, 3% closing, 6.75% for 30 years.

1. 1Projected value = $300,000 × 1.03³ ≈ $327,818.
2. 2Rent-to-own: cash = $9,000 + $2,100 × 36 = $84,600; credits = $10,800 + $9,000 = $19,800; equity = $327,818 − $300,200 ≈ $27,618; net ≈ −$56,982.
3. 3Buy now: $30,000 down + $9,000 closing + about $2,410/month × 36 ≈ $125,744 cash; balance ≈ $260,750, equity ≈ $67,066; net ≈ −$58,678.
4. 4The two paths finish within about $1,700 of each other, with rent-to-own slightly ahead — a small change in appreciation or the agreed price flips the answer, which is why you should test several scenarios.

Is rent-to-own cheaper than buying?

It depends on the option fee, how much rent is credited, the agreed price versus the home's future value, and mortgage rates. Rent-to-own is often more expensive in total, but can make sense when you need time to repair credit or save a down payment.

What happens to my option fee if I don't buy?

In most agreements it is forfeited, along with any rent credits. That is the main risk of rent-to-own, so compare the net position at 0% or negative appreciation too.

Why compare net position instead of monthly cost?

Monthly cost ignores equity. Buying now costs more per month but builds equity through appreciation and principal repayment; net position counts both what you spent and what you own.

Does this include the mortgage I need after exercising the option?

It shows the loan amount you'd need at exercise, but the comparison stops at that moment. Costs after purchase are similar for both paths once you own the home.

Is this legal or financial advice?

No. Rent-to-own contracts vary widely and are regulated differently by state. Have the agreement reviewed before signing.
