Sell Decision Tool
Compare two simplified paths:
sell now and invest the proceeds or
keep the property as a rental for a few more years.
This is meant to help with an existing-home decision, not a full buy-vs-rent analysis.
Inputs
Estimated fixed monthly carrying cost
$0
Mortgage payment + property tax + insurance/HOA + repairs, before rent-linked costs.
Estimated monthly rental cash flow
$0
Rent minus carrying cost, management, and vacancy, plus estimated tax benefit.
Current Property
Loan Details
In manual payment mode, your entered monthly P&I drives cash flow, while mortgage balance, rate, and years left still drive the estimated principal paydown and future equity.
If You Keep It
Estimated current payment breakdown: interest $0, principal $0.
Growth Assumptions
This is a simplified sell-vs-keep tool. It uses a rough optional annual rental tax benefit input, but it does not model full taxes, depreciation recapture, refinance options, or future mortgage amortization in detail.

Ending value by year
Blue assumes you sell now and invest the proceeds. Green assumes you rent it out until that year and then sell, with interim cash flow differences carried forward over time and any optional rental tax benefit credited annually.
Advantage by year
Above zero means selling later is ahead of selling now at that year. Below zero means selling now is ahead.

How to read the outputs
- Sell proceeds today is the amount left after selling costs and paying off the current mortgage.
- Monthly rental cash flow is the estimated monthly cash flow if you keep the property as a rental right now before the optional annual tax benefit credit.
- Suggested choice today looks across the years shown and tells you whether selling now or holding for a later sale produces the better result.
- Best later sale year is the year where renting it out and then selling produces the biggest advantage over selling now.
- Minimum hold period to justify selling later is the first year where selling later gets ahead of selling now.
- Methodology assumes sale proceeds are invested if you sell now, and also carries forward ongoing rental cash flow over time. Positive rental cash flow adds to the keep path; negative rental cash flow acts as an ongoing drag that could otherwise have been invested. If you use the rental tax benefit input, that benefit is estimated from deductible rental expenses and credited annually rather than compounded monthly.
- Use this tool directionally. Small changes to appreciation, rent growth, selling costs, and investment return can change the answer a lot.
What this tool does not model
