With a regular, regulated lender neither one is legally possible and wouldn’t meet fed/state banking regulations.The current lender will either give you a discounted pay off, or they won’t.....that is your only solution to refi.The deferred principle makes this sound like a loan Modification done by a major lender.....not sure what a “balloon payoff penalty” is, sounds you are mixing up terminologies.

Example objective in this scenario is going from 2 flips a year, to 4. 

PM me of the details of both your objectives and counsel you are seeking.

The only difference is I’m doing all 30 year loans and just paying down extra principle.

You'll also benefit from tax advantages, potential appreciation, and principle paydown.

This is a shiny object of distraction, rationalized to look better than lipstick on a pig.

I mean, that's the whole principle behind the BRRRR strategy isn't it?

Eventually the LPs sued the GPs (mostly because of me) and we recovered the principle amounts plus legal fees but it took almost 10 years to get the money back.

As a side not, I am not sure development achieves what their objective is.

Happy father's day I guess.So my main objective is to get him out.
