Hello,I am signing an agreement with a property management company for my rental.

I understand a parent/holding company is the next level of protection when you have multiple LLC's. 

I prefer bank statements.

I'd prefer have a company do this for us unless it's simple enough to run on our own.

Absolutely find a lawyer familiar with HM/PM and do not rely title companies or anyone else.

She mentioned at 38:38 timemark in the video.she mentioned that one of the units had a year commitment with a payment of $44k (I guess it is company paying for one of their employee tenants)How realistic is to make $80k / mo profit with this kind of capital?

Generally speaking, the buyers in the USD market (foreigners and wealthy and upper middle class Mexicans) want a new or turnkey property and don't want to have to do renovations and they prefer new properties over properties that have been renovated.

The appraisal of our house from our refinance company came at $60,000.

Still lots of people and companies moving here. 

I also started a general construction company less than a year ago and gotta keep my team busy!
