I imagine this would take close to a year if all went well, and eat up a lot of funds.

An out of control litigious society, and the things that really eat up modern family wealth have nothing to do with what consumers would expect.

Now, I could get a 0% loan through the mass save program for 50k of that over 7 years and come up with the rest out of pocket, but that would eat into a good chunk of my cashflow. my thought is that its not worth it to put the 70-85k into the property and might be better to sell it since I could probably sell it now for about 100k more than i paid for it.

My goal is accumulate properties while I’m still living at home, to eventually be able to fund building my own house with the cash flow from the properties.You are going to need 20-30 percent down then which will eat your savings.

If my cash flow was not strong enough to weather them moving, I'd eat the tax increase while considering a 1031 or an outright taxable sale, both of which I've done. 

People need to eat and pay rent.

In Southern California, multi-family properties offer potential for appreciation along with some cash flow, given the steady population and desirable market, but higher property costs, taxes, and insurance can eat into your profits, and finding a suitable unit in your budget might be competitive.

And we dont eat pizza..

Yes, we flipped it to get a chunk of money to invest in other properties, but the chunk somehow slowly disappeared taking care of 3 kids, eating out, etc.Maybe what I learned is to get your financial house in order first. 

Also, Ive bought office supplies, went out to eat with contractors, and more, should I be using a business credit card?
