That’s the best bet.

FB ads/marketplace proved far more efficient than craigslist/some of the other platforms I've used for rentals in the past.

SD market is tough for cash flow, at least when you initially purchase the home.Your best bet is a live in flip / house hack, meaning you buy a house in need of some love in a nice neighborhood at a discount, fix it up and then house hack.  

Your best bet is to buy a multifamily, live in one unit for a year, and rent out the other units. 

Whether be from the courthouse, or website platform. 

If you plan on using your VA loan (which I highly recommend for a house-hack) you have a few options: Your best bet would be getting a full time job lined up immediately after your EAS.

For my personal portfolio I use Cozy.co which is free to use.For my client's commercial office portfolio I use Yardi Breeze which is more of a Property Management, Maintenance, Accounting, and Leasing platform that has a $100/mo minimum.

I don't know the average time on market there, but would bet it's in the 6-12 month range.  

If you expect to use it for another property and pay back the "loan" over a few years, the REFI is probably the better bet.

I bet the concrete is not dense with aggregate, and aggregate is like pebble river rock instead of crushed aggerate.
