Or paying off my debt, while I provide them with a nice house to live in instead of an apartment. 

I am mainly in the West Palm Beach area.  

If not, they may consider building the ADU and down-sizing into it and renting out the main house.

I make around $110k+ per year, live off around $75K, have a mortgage ($1900/mo for rent, escrow, tax), around $40K in equity, and no other debt. 

OKC has alot of opportunity mainly because of its low level of enforcement of housing codes, strong landlord laws and conservative judges in eviction court.

I believe it to be a little Southern California hidden treasure for cashflow, mainly class C but if you know what you are doing its a really good option to invest locally in CA with decent returns.

I mainly am curious how people have raised capital for their first properties. 

Great location on main hwy. 

A good DST would absorb the rest of your debt nicely.

I have very little debt besides mortgages and have spent my own money doing renovation over the last few years.
