However, my wife seems nervous a little bit to have a lawyer as a tenant, concerning their may abuse their professional advantage, victimizing the landlord and leading us to a possible vulnerable situation, as they may pick up on any tiny issue to make a big deal.

The same can happen with a flip or BRRRR  strategy assuming the investor has a competitive advantage and can do, or get certain jobs done, quicker and/or at a discount compared to the rest of the market.

There is being nice and being taken advantage of. 

Just to play devils advocate - It may be worth looking at taking the tax advantage of living in the house and not taking any capital gains tax when selling and capitalize on the current crazy market and go buy some better cash flowing assets in areas less expensive with better rent to purchase ratios.

So, you may want to get them involved on any purchase ASAP, for their feedback before you sign a purchase contract.Regarding selecting a PMC, they can make or break your investments!

I have the idea and the advantage that we ourselves can flip the homes for more profit but the only barden that’s stopping me is funding.

I want to take advantage of my good credit score to get a residential mortgage, and then transfer the property to an LLC that I'll open together with my partner.

FHA financing will allow you to buy up to 4 units with advantageous financing and low down payment. 

Like any other government program there are going to be people that take advantage of the system to get free money.

Do you select any tenant base that can withstand hyperinflation?
