Here's a typical call:Buyer (You): Hi my name is (your name). 

@Steven Catudalthe 'no cash flow on a BRRRR' is typically just because you are boosting the ARV and then taking out the maximum amount you can on the refinance, often using a DSCR loan with a higher rate. 

You're better off opting for an interest-only mortgage, saving on payments, and then refinancing it into something more conventional when interest rates drop—or, if possible, making a plan to pay down the principal.Interest-only loans, which typically last for the first 5 to 10 years of the loan term, offer two key benefits.

While short-term rentals in areas like Kissimmee, Florida, can pay for themselves and offer lifestyle benefits, the ROI typically doesn’t match what I see from my traditional portfolio of long-term rentals in North Texas.That said, short-term rentals can still be a great choice, especially if you're drawn to the area and the opportunity to combine personal use with investment income.

If this is the case then typically you only have to comply when you make alterations.2.
