Bill Hit the nail on the head, sorry.

Original idea was to remove 2 layers of siding, but engineer said he didn't know what was behind the original siding and how it was nailed down so we had to remove it down to the diagonal ship lap that was common on those older houses.  

The shingle nails need to go though the wood to hold properly.

Lots of nail holes in the walls, bumps, nicks, scratches, broken cabinets, windows, railings etc...  

You need to be able to nail down your variable expenses and correctly anticipate CapEx. 

Ultra high net worth are generally more focused on capital preservation or very long term, where the more typical accredited investor is often in growth mode trying to hit doubles/triples/home runs, and willing to take some additional risk to get higher returns.  

Are you screwing (removable personal property) or nailing (building improvements) in artwork?

Tenant moved out and left countless large wall and nail holes / baseboard damage / drywall tears due to adhesive removal, etc. 

Once I nail this down, I'll be looking to build a team and buy from a whole seller or off market.2.

The previous posters nailed it, look into "house-hacking" as they like to call it on BP or buy a rental and continue to live at home.
