If they decline to share, that is a red flag which would warrant walking away or at a minimum substantially reducing the price instead and basing the offer on your own numbers validated by third parties.

Maybe they call you and ask a question or two.

I was envisioning a two part calculation for the monthly mortgage payment - I see it as a VA loan analogy with no money down but the loan structured with two interest rates (one for the TSP down payment and one for the 30 yr fixed rate mortgage).I guess the real question to ask myself (using your situation as the model, assuming positive cash flow once TSP is repaid) is whether I am okay tolerating the potential 60 months of negative cash flow to get to the positive cash flow after 5 years.- Maybe if it gets the deal going and leads to a cash out refinance before the 5 year mark that allows me to speed up the TSP pay off.Wow - Great food for thought. 

Maybe a purchase or two from them as consideration.

Two real estate agents I've talked to in two different cities are not finding very profitable deals.What are ways you use to compare markets and find the best one for you?

Preferably the one or two properties with the lowest values so you can increase the overall average for the value of the property.

We own two single family rental properties and an ADU in our back yard.  

I may know a resource or two for you to check out...Cheers!

That will fix his wagon.I see two problems:1.

I think your negative cashflow will be higher.There are only two ways you win:1.
