If you hit a time limit you have for yourself to sell and still haven't had offers, that would be a good time to start answering the endless stream of phone calls, emails, and door knocks you'll get from agents looking to list for you. 

My goal in real estate is to own mobile home parks, multi family homes and try fix and flips.

It’s totally strange, they refuse to talk on the phone with us and are quite hostile. 

Payment history on your utility bills, cell phone, and other types of bills can be used to establish credit. 

(You'll learn a lot by hopping on the phone with these people)3.

I’m sick and tired of having my mailbox full of these “I am buying houses cash in your neighborhood” letters, but the worst is the constant phone calls asking me if I want to sell. 

I gotcha thanks my phone hasn't been pulling it up like it wasn't posting and this time I seen it and came back thru an email.

But it doesn't hurt to pick up the phone and start calling local offices. 

Get an estimate over the phone and don't use that GC again.

I have potentially started in multi family investing at the commercial level, then expanded to self storage in mobile home parks.
