Accelerated depreciation, taxable income forecasts, and running various numbers/scenarios.Point is that tax planning/financial planning is not the area to skimp.   

@Brian Larson Kudos to you for thinking outside of the box and problem solving a housing need. 

I have a son 2 years younger than your son… How did you go about moving your son along towards financial independence?  

Then without knowing your entire financial situation I’d probably prioritize getting that paid off over putting anything in a Roth or over and above an emergency fund in a HYSA. 

For a partnership where you're providing all labor and the broker is funding the deal, a fair split typically ranges from 30-50% for you and 50-70% for the broker, depending on the value and complexity of your labor versus the financial risk they're taking.

This is an ongoing tricky area for DSCR Loan refinances that is far from solved (although we are working on it!). 

Generally speaking solid insurance and a good umbrella policy will provide ample financial protection for most liabilities.

So creating all these funky financials is great, but if you are using those in a presentation that information should be in the PPM or an official document as if someone is making a decision based on that - it can come back to bite them.

When offers come in, prioritize pre-approved or cash buyers for a faster closing process, negotiating where needed to maximize your profit.Finally, conduct a post-sale analysis to evaluate your financials, noting how actual costs, timelines, and profits compared to your initial projections.

And make sure you have the financial resources to handle that.
