It will be a DSCR loan, under your US entity or personally held.

If they know that you changed ownership, they may call the loan due.

Not looking to refinance due to the great interest rates  4% on 30 year loans but would have not talked to any lenders that will do HELOC's yet.   

My question is that if a deal has a mortgage subject to an existiting loan and a private lender funds the purchase of the enry fee (wholesaler fee/agent fee/cash to seller/etc.)

You sit and you wait....With new construction waiting isn't as bad a renovation because your holding cost is around a 7% rate, where as a renovation you are probably on a hard money loan at 12-15%. 

Can definitely get no income no doc construction loans that would allow for it 

I don't need a downpayment because I have yet to utilize my VA home loan, I want another townhouse or SFH in the San Fernando Valley because of where my job is currently located, just makes everything way more convenient for myself.

BTW, you must get a phila tax ID first, then a commercial activity license, and finally a rental license.Hope this helpshttps://www.phila.gov/services/permits-violations-licenses/g...https://www.phila.gov/services/permits-violations-licenses/g...https://www.phila.gov/services/payments-assistance-taxes/tax... 

Would this help me at all when it came to the tax on my flip @Michael PlaksIt will help you qualify for a better loan. 

@Noel Dixon The most overlooked thing I see when people talk about assumable mortgages is that, if you can get approved by the lender holding the mortgage, you will need to bring the difference between the loan and purchase price in cash.
