I have suggested in the past that a good lawyer will be able to pierce just about any corporate veil and a good umbrella liability policy may be a great alternative. 

This person in particular is not local to me so I feel uncomfortable trusting they have "done millions in transactions", and I don't know what type of materials to ask them for to prove legitimacy.

Alternatively, you are putting your investment in the hands of an operator with an apartment syndication, but the company managing a large apartment complex is a professional organization managing potentially thousands of units.

What materials should I look at daily!

After much research, planning, goal setting, and purchasing my first two SFR with the VA Loan while moving around duty locations with the Army, I finally took the first action step of building my multifamily portfolio with the purchase of a Duplex several months back.As I begin to build momentum with my purchases, I want to develop a "template" or rather a material list with (color / type / brand/ price / vendor) that would serve as my go to for items such as paint, types of blinds, carpet, flooring, hardware, ceiling lighting etc..

This is especially true in the current market where there is a shortage nationally and you are paying to dollar for labor and materials.

The subfloors are typically a composite material and any leaks or moisture inside can rot them quickly and they crumble.

We also go on to list different examples of negligence such as clogged drains due to improperly disposing of materials such as grease, sanitary napkins, ect AND changing furnace filters, batteries.

If they are nice enough to agree to do them, you shouldn't expect them to also pay for any alternative housing or the storing of your furniture.  

Also, people are seeing vacation rentals/private residences as much safer alternatives than hotels and able to adhere to the social distancing guidelines.
