It repeals an important California rental housing law with no replacement and no plan to address affordable and middle-class housing or deal with the problem of increasing homelessness on our streets.

One idea I've come across is to refinance out of my current FHA and try to get another one with 3.5% down, but I'm not sure how plausible it is to get another FHA Loan without an increase in family size or geographical job change. 

If you were ok with taking on additional debt (loans your tenants would pay down for you over time), you could potentially leverage that 475k into 10 or more cash flow properties (though there are limits on how many loans you can carry at once).Of course, there's always a middle ground too: sell the condo, use some of the money to increase your DP on the new house and use the rest for investing.

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.

I have also seen that it is becoming increasingly difficult and more expensive to get involved in Airbnb in Miami Beach but other areas in the near vicinity have great potential. 

If you do not have an agreement on maintaining the rent, I suspect he can increase it. 

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.
