Unless your plan is exhaustive enough that you have every single line item covered and you can create accountability for each contractor who steps foot onto the project, you're bound to face bottlenecks with this approach.

Assuming all of this is true, especially the list of lenders as noted above (and not for example a "lender" under a Deed Contract or Installment Note to Mom & Dad, Aunt Judy or Farmer Bob),  and assuming that we're not in an absolutely rural locale, where the REI/Wholesaler actually may have a better network than an area's licensed Agent from 5+ miles away... ...Then what possible value could a wholesaler actually add **from a Lender's point of view**  in an REO transaction?   

These are just a few things you can start with and is no way an exhaustive list.

Over four units and once you've exhausted your 10 Fannie/Freddie loans (each of you can have 10, provided each has income to qualify and owns the property only in their own name) you're into commercial loans. 

This is not an exhaustive list, but hopefully a good start. 

Sounds like your scenario is more of a luxury purchase than an investment. 

We do not want to exhaust all our cash reserves..

It's more to asset and debt management than an amount of equity.

In addition, if the depreciation deductions have been exhausted, it might make sense to 1031 exchange and move on to another property.

I suppose every county calls their tax assessor/collector by a different name.Mine, which is a small county, has an exhaustive website that even includes legal notices and tax lien information.I don't know Tampa, but that's where I'd start.
