Such as moving to smaller home for less rent, selling your car and buying a cheaper one, cutting out extras in your budget such as take out and eating out, etc...If you can make sacrifices now by redicinf uoir bdieht ane/or increasing your Income you will be able to prosper in the near future with real estate.

Many of my plan's decisions can be deferred (I'm trying not to overwhelm myself with planning specifics) but it seems like if I need to show specific experience to a bank, I'll need to start building out my resume at some point.My next step is to increase my cash savings to prepare for a purchase in 2019/20.Any books you'd recommend?   

Can you increase the rent on the section 8 unit?  

First you need to continue to increase you investing capital. 10-15k is a great start, but it goes quickly.

It's a rental so unless it will increase rents it is not really worth spending the money on a nicer fence.

I would also call your credit card company and ask them to increase your credit limit.

Based on that, I can see that demand is high and I probably have potential to increase the rent.Best of luck!

That brings their total return up to $64,400/yr or a return of 47.7% per year (I know, I know, I didn't factor in the increasing cashflow - I did that to be conservative).
