Unless you bought RE a few years ago, created equity via successful BRRRR, flip, or do a combination you're just playing the appreciation game. 

Did you know Booking.com has 4x the visitors to their site than Airbnb and VRBO COMBINED? 

Partner Driven funded this transaction by leveraging a combination of internal capital and strategic partnership resources.

That, combined with hidden repairs combined with self-managing a low income could all construe to thousands in losses. 

Most criminals defrauded the IRSI wonder what would happen if the people who combined lost like $2M all sent 1099's to him-I bet that would wake up the IRS but not sure if it would impact their claim later on.

When funding is plentiful and flips are rare, the competition will be heavy and experienced flippers with teams will take smaller returns just to keep their guys working, which means inexperienced 1-man crews will be shut out of the market.

Your first deal in real estate is rarely your best deal, but you're creating opportunity for yourself. 

Quote from @Tim Johnson: Has anyone seen an example of a lender combining debt with equity on a real estate deal?

The combined cash flow and appreciation from these new investments could potentially surpass what you're currently earning, even if the immediate cash flow isn't as strong.

I personally use my HELOC now to help with quick acquisition in combination with my 100% purchase/100% Reahb hard money loan and then i just pay it back off at the end of the BRRRR.
