Or just a lawyer for the paperwork?

I’m not opposed to paying the money to speak to a lawyer, Im sure in hindsight there will be many learnings from this!

In the end, it comes down to whatever advice you decide to take from your lawyer.

I will definitely be contacting an SEC lawyer.

I'm no lawyer, but I believe any rent change for any reason needs a new lease, unless it's a month-to-month.

I have, 2x, by people whose lawyers  saw someone with a few buildings and figured they have lots of money.  

Also you need to get your fee out of it.I do not know the specifics but honestly that deal seems WAY too skinny for me.3) You still need to add the cost of doing RE transactions, lawyer fees, closing costs taxes, holding costs , lawn care, utilities, insurance , lending costs .. etc. etc.

I will mention it to my lawyer.

i'm looking into BRRRR strategy that in a certain way could speed up of portfolio growing. in case of No US citizen re-finance could be an issue or registered LLC in US with lawyer with power attorney could be sufficient to have money from bank? 

There’s no problem anticipating that rentals will provide for your family there’s 3 things to consider:1) legally set up operations so that your beneficiaries can simply continue them without any kind of weight of going through probate (other wise a little life insurance for probate season can be helpful- this should really be a conversation with your lawyer if you have questions about probate - thankfully @Pat L.’s doing the right thing with the trust).
