But lets say the property does not appraise in 5 years for more and the initial balance is higher than the refinance loan amount, then he will need to put a downpayment to close on the refinance. 

As The title says how would i go about wholeselling at 15 im doing it but how do i sound more professional and confident talking to a seller/buyer because they see my youth as i dont know anything i know a pretty good much about how to wholesell how to find everything but since im so young i dont know how would talk to them without throwing the deal(ignore my name getting fixed)

You are only putting 5% down so your loan amount is much larger and therefore your mortgage payment.I would consider your net worth ROI.

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. 

What is your ROI and the amount paid for a cost seg study?

I would then issue a 1099 to each owner for the amount of rent payed to them. 3.

When you go back in to your listing to "fix" this, there is an option for "sleeper sofa".  

First, how much will it cost to fix?

Most who come here looking to do arbitrage don't have anywhere near that amount.

The seller (also a local agent that sold his home himself) disclosed there was a roof leak and was fixed in July 2023.
