Plus new folks do a very poor job of screening the buyer for Ability To Repay (ATR) which involves pulling full doc and calculating the borrowers DTI, honest income, honest debt payments, prior debt payment histor (FICO) etc etc.Plus shockingly (or shocking to sellers) if you bought this investment house, fixed it, then are selling with financing you are selling "inventory" and y9ou owe taxes on the gain in the year of sale, you are NOT able to use installment sale to spread out paying taxes. 

Hi,New to BiggerPockets.  I have a few lots in New Orleans and am looking to run  profitability analysis of sfr 3/2 development v. one zoned as duplex.  What are the best Bigger Pockets tools to use for profitability ...

You will also need about 6 months of reserves deposited in a traditional financial institution rather than a crypto account.The next step is to find the target property and calculate the acquisition costs and costs of construction along with the after-repair value. 

Tools like the BiggerPockets calculator and books like The House Hacking Strategy can guide you further.

Not all lenders are well-versed in these calculations.

BiggerPockets also has a calculator to analyze deals, and I highly recommend you start this as soon as possible, even if you are not ready to buy.

A Title Company can distribute the proceeds based on the agreement, and consulting a CPA will help calculate tax liabilities and explore strategies like a 1031 exchange to minimize taxes.

A good baseline is to calculate material costs (e.g., $300 for paint and supplies) and add a fair hourly rate for labor.

@Dav idWithout going through the numbers again, my guess is your calculation goes astray at the calculation of the Heloc costs.
