Here's another one:  Went to a Tax Sale where there was a "vacant" lot for sale of about 1 acre in a desirable suburban area. 

At $500/mo per door you would have $175,000 cash flow in a year before operating expenses.

For example in a hot area of Houston I have a 30 unit. 20 of them are in a courtyard and 10 face the street.

I'm speaking of co-living in a typical A or B level neighborhood house, so instead of a 20-25% down payment, we are speaking of a 1-5% down payment. 

If I buy property in a state that I don't live in and put that property into an LLC registered in that state, will it be protected or does that LLC need to be conducting some form of business?

I am in a pickle right now because my mom is turning 80 and not very active.

Whether that's through the application/leasing process to communicating with owners and vendors in a timely manner to address anything related to the property. 

In a TK--they basically sign over control & overpay, but don't sign over equity. 

I spent 5 years tutoring in a 'hood.

If approved, you’d already be in a position to add units, whereas others might still be navigating the zoning process.That said, rezoning takes time and isn’t guaranteed, so it’s worth weighing the cost, process, and likelihood of approval.
