You can do delayed financing for the whole project, without seasoning.

I believe here in Florida the contract actually remains valid and the estate representative handles the closing (albeit with possible delays depending on probate). 

Our goal is to get a 2 - 4 unit property, with minimal rehab needed, already rented units (ideally), for around $50k.

The renovations are minor and will allow me to do a delayed mortgage and recapture most (if not all) of my capital.

They are the gatekeeper for all plan transactions, with the resulting paperwork, delays, and cost that go along with that.You may wish to evaluate the Checkbook IRA LLC or Solo 401k (if you qualify).  

This way you waste minimal time, and essentially cast the widest net.

Sorry for the delay in getting back to you.

We had it under contract for over a year because the builder kept experiencing delays.

I rehabbed the two units myslelf with minimal improvements.

After 2 year seasoning you should be able to purchase when the master lease is up or work out an owner finance deal where the owners like the idea of delaying capital gains taxes.
