We are currently looking at refinancing to get out of the PMI on our first and primary residence, and I saw a "scam" on replacing your mortgage with a HELOC and you'll pay down your mortgage in 5-7 years without doing anything!

Your refinancing costs + new fha loan would be about the same as just using a 5% conventional loan for your next property.

Further, a paid off purchase does not preclude me from refinancing in the future.

Some DSCR lenders are stepping up for BRRRR investors with lenient seasoning periods and the 1.0 DSCR minimum, making refinancing much more accessible.

I have refinanced those to 85% loan to value with a credit union and got over 10% back out which was about 200K. 

Refinancing  immediately prior to a sale - yes that is a cause for some seasoning. 

Plus, we are now refinancing all the Money we invested total out.  

I can't remember, but it turned out that since I kept paying my broker 1%+ every time I re-financed my principal never decreased.

Even if it's not, nobody said anything about forcing a situation and everything can be refinanced later?

Fixed them up...refinanced...."
