Advice needed on combining LTV’s and new construction.

[Perry Ivy]

I have long term rentals and am now about to launch my new construction business. I would like to roll some of my profits from the new construction into buying more long term rentals. I’ve consulted with my tax accountant, tile company, a few other professionals and have been told that it is possible, but I’m not understanding how it works. Could someone explain the process? Thanks for your time.
