If you have a working calculator to share for either or, please let me knowThank you in advance!

And definitely include a contingency reserve for unexpected issues that come up during the project.Overall, it sounds like your calculator is shaping up to be a really useful tool for analyzing deals realistically.All the best!

Quote from @Keith Meyer: Hi All,I'm looking to see if anyone knows of a calculator/modeling tool which can help me compare the benefits of selling a property with these four options:Sell and pay capital gains/depreciation recapture upfrontPerform 1031 exchange into new property, defer taxesSell on Seller Carryback Installment Sale, defer taxesSell on Monetized Installment Sale, defer taxesSurprisingly I couldn't find anything online which was very helpful.

my calculator is not working correctly when inputing numbers larger than 4 digits...

The profit calculations would be your adjusted cost basis (purchase price, plus capital improvements, minus depreciation), subtracted from the net sale of the property (sales price minus closing costs and commissions), like others mentioned above.

It seems like a great majority of the calculators here are behind a pay wall.

It's been several years since I have used bigger pockets, even though I paid for it. We flipped several houses since last time I used it and when I originally started paying for the pro membership, we wanted to get in...

We need more clarity to help.Step one is a breakeven calculation.

It would be illegal to start your depreciation over from year zero.Your depreciation schedule is calculated from:The original purchase price Plus capital improvements Minus land value (which isn’t depreciable)That schedule doesn’t change unless your basis changes.Yes, your amortization schedules should change, but I don't see how a refi itself affects your basis.

I calculate with extra principal payments I'm comfortable to make I can reach that in 3 years while saving for another down payment for fourplex.
