I understand that VA loans are assumable, but I'm unsure how this affects the original borrower's ability to use their VA loan benefits in the future.

Thanks  I'm assuming thus was an owner occupant loan since you received a grant.

I have multiple sales closing next month, but have a situation where Im cash strapped and personally need $5k for less than $30 days.Does anyone do these type of loans not based on credit and fund fast?

If there is a mortgage for example, you have a debt but it isn't like you can just pick up the payments because you have no legal standing to deal with the loan.

Proof of Funds (PoF), Conditional Loan Agreements (CLA), Letter of Intent (LOI) are all attempts to show that some kind of financing has been investigated and is feasible, that's all. 

It's not 100% clear, but it sounds like what you're asking is how to get loans while you have a low credit score.

security, fencing, a guard dog inside or someone stays there at night $1500carry cost of your loan/tax/insurance$?

Consider it as a baseline, says Quicken Loans: When you sell the property, the cost basis is subtracted from the net sales price to determine capital gains tax liability.

So it may be better to let someone else do the heavy lifting and take most of the risk (i.e. they be the sole guarantor on a construction loan, etc).

Or do I just use the remaining balance of the loan?
