Looking to start purchasing homes for buy and hold rentals, I'll probably do a cash out re-fi on my primary residence.

If you're serious about expediting the process to FI, sell the car and get an old dependable car in the $5k range. 

The thing I don't like about these is you have to re-fi at the end of term and it restarts amortization and you incur more closing costs.

But I’m just wondering how long it took you all to reach FI

I'm curious as to what interest rates my fellow B-P'ers are getting for SFH re-fi's. 

Even if I can invest the remainder on justification of the rental income vs. operating costs, it will need to be mostly with funding that can be sustained long-term, because the re-fi I'm sure will be dismal.

Semper fi Michele, If you put 20% down on the property, you should be able to refinance with most banks (provided the seasoning period is met).

Semper Fi @Enrique Montalvo Jr, You can, but only for the amount they don't have a mortgage on.
