I was pre-approved for a conventional mortgage with a 3 % down payment 2.75 Interest Rate.

When I asked them about the fraud/lawsuits they said that was Clayton Morris' old partnership with a different company and now they only refer to SDIRA Wealth which only sells new construction homes that are usually pre-leased to buyers (currently they are building in Lubbock, TX).

Pre-internet, being a landlord wasn't easy, but it was straightforward (this is a gross oversimplification).

Watch out for the village requirements and make sure your team knows what areas require rental and pre-sale inspections. 

Get pre-approved for a buy and hold loan- It could be multifamily, single family.... depends on the market3.

Also Ca tax sales wipe EVERYTHING out the only reason for a pre lim would be a access issue.. which of course one can do on their own..

I spent well over 1 mil on a CRM, owned a rock solid direct mail provider and drove a Rolls Royce.  

Also have you done any pre-dd-  driveby, discussions with broker, property managers and other real estate professionals about this property.   

Lobster rolls and Lobster Ceviche. 

I'll add, since you're pre-closing it's worth reaching out to the seller/current property manager to see what they currently do.
