I have refinanced (rarely mind you as there are costs that take years to recoup on a refi) and am happy to see equity build as the mortgage shrinks.

DSCR loans let you qualify based on the rental income of the property rather than traditional income verification.

You can read a book and multiple books, but unless you are out there doing it (I.e. getting bids and getting contractors to truly get you an exact estimate) you will be far off from the numbers you want and may even lose money on the flip/rehab.The best advice I would suggest in my experience is that you should get into the line of work by either partnering with someone or working with someone on some projects prior to going into a flip on your own.

The mortgage would stay under the seller's name.The buyer could then rent out the unit, renovate, etc. to increase cash flow or make more money.But aside from a possible "due on clause" being called by the mortgage company, what's the benefit to the seller?

Private mortgage insurance i believe is not charged on va loans.  

(not sure on state law but this probably is a tough sell)4.

also:don't give up on house hacking.

Retain a cash reserve to cover vacancies or downturns, and align with your long-term goals by consulting a financial advisor.

I am getting ready to close on a property in the couple weeks.
