We paid cash, and got most of our supplies from habitat restore, salvage stores, and clearance markets.   

Of course I am understanding of the circumstances, we're still in the middle of a pandemic so staffing at their office was frequently an issue, supply chain shortages and backlogs of necessary equipment, winter was upon us and the ground is frozen.

Challenges?

As we're all aware, supply chain issues are real and construction is indeed backed up quite a bit in many areas.

Toilet paper, cleaning supplies, coffee, towels and sheets, laundry detergent, etc.  

Here is what I am looking for.Name of the company, Location of the property, Any challenges, How to screen them?.

Challenges?

While that may be daunting, the increased returns will offset the challenges distance may provide and provide diversification to your holdings.  

Or are you debating whether to push for the FHA but run into the challenges that loan type may impose?

I am not sure where you are located, but finding deals in Huntsville/Madison is a major challenge right now;  you may be better off looking local if you are out of state.
