Housing & real estate

Rent or buy, refinance, and evaluate rental and flip deals with the numbers lenders use.

Housing decisions combine large numbers with long time horizons, so small assumptions compound. Compare renting and buying, test whether a refinance pays back its closing costs, and run rental or flip deals with the same metrics lenders and appraisers use.

Calculators

RentBuy Desk

Rent or buy? See the year it flips.

The rent-versus-buy question is full of hidden costs on both sides: maintenance, taxes, opportunity cost. We put them in one model so you can see the break-even year for your own situation.

RefiPoint

Is refinancing worth it? Find the break-even month.

A lower rate does not always mean savings once closing costs are counted. This tool finds the month when a refinance pays for itself, so you can decide whether you will stay long enough to benefit.

RentalROI Desk

Cash flow, cap rate and DSCR for rental deals.

A rental can look profitable on rent alone. Counting vacancy, repairs, management and financing shows the cash flow and return that remain, which is the number that matters for a decision.

FlipDeal Desk

House flip profit and the 70% rule.

House flips fail when small costs are left out: holding costs, financing points, a few extra weeks. This tool adds every line so you can test the maximum price you should offer before you fall in love with a property.
