Anyone from car sales to real estate investing (self employed)

[Jimmy Rojas]

I been in car sales since 2011, started working for my brother in his used car lot , then on 2016 to present day i became self employed, still in the car sales field, buy vehicles at dealer auctions(using a DL license) and put them up for sale in my brothers car lot , once i leave the car  they are in charged of advertising and selling the vehicle, i do small scale usually ill have 5-12 vehicles on the lot ,  dont make huge amounts of money but enough  to be self employed semi retired and live a life style that im in total control off.

I been eyeing real state for sometime now  but in my situation don't know how that is even possible as being self  employed don't have proof of income, most of my money is tied up in my vehicles , so don't have too much liquid cash and dont want to get screwed getting a hard loan  or getting a loan from my brother, also the fact that in Az (PHX) home prices are still crazy high doesnt help.

Like i mentioned before i know nothing of the real estate field but im assuming the process of selling a home takes a lot longer than selling a car .
