Quote from @Omar Mares: Wholesaling doesn't require a license because one doesn't exist.

The existing business would be wound-down by the current owners.  

Since I like wood working, and have made several cabinet boxes for other rentals that needed repair to match existing cabinets, I can always cut new sides & bottoms if/when the presswood starts to deteriorate, and reuse the frames & doors. 

From a house hacking perspective there have been good options around 400k because you can get more per room than renting out the whole house, especially for mid term rentals.i don’t think any real deals exist anymore- just cheaper than nearby Frederick County. 

I do like the idea of buying a home where everything is still under warranty, although the idea of buying something that doesn't exist yet gives me some pause.

We have an existing 5 car garage which I plan on converting into two ADU’s, and an existing 400 - 500 sq.ft conditioned space that is currently not being used for anything.

definitely. i have got the details from them for their existing landlord. however, that name does not match the owner on the city tax office property records. and they have confirmed that they provided the landlord's details, not the property manager's details.I believe that should match or it is possible to not match?

Commercial lending terms would apply.The 80/20 or 80/10/10 loan types are no longer in existence.  

When adding a second rental property to an existing LLC, you can generally deduct start-up costs and operational expenses. 

Not as much as multifamily but still more than STNL single tenant or 2 to 4 tenant type retail center properties.The larger centers they live or die by the anchor tenant so really have to know if that tenant owns or lease the space, when it was last re-imaged inside and out, and what sales they do per sq ft year over year and how they have been trending.Larger retail centers have defaults from smaller tenants with covid right now to work through so offering should have reserves built in for some not making it so buy in cap rate on existing NOI might go down in the short term as tenants are lost and tenant replaced.
