You can try to act as a PM and guest comm from afar but its tough without seeing the physical product sometimes.

That is because the price of new construction increases as material and labor costs increase. 

I checked BBB , could not find anything material.

It's tough, but you can do it! 

Within the next year, ill be doing work to the property laying down some sweat equity.My question is this: In everyone's experience, has nicer (not the cheapest builder-grade stuff you can find) materials translated to attracting a more qualified and responsible tenant?

It is tough to make the single family properties cashflow, and small multi's will cashflow but are in a higher price point, and can require a lot of deferred maintenance.

I invested about 10k in materials on the rehab and have since been slowly updating the house. 

Hi Nicole,LVP is the most well-rounded material on a cost-effective basis.

I have a builder out today who is going to add in some supports until we can get material to reframe the front of the roof.

And when the last guy in the chain can't find a buyer, it's the direct to seller wholesaler, who has spent a lot of money and time to find the seller and market to them, that has to have that tough conversation with the seller about how the deal fell through.
