If you combine the consistent track record of growth and projected growth based on future developments in the area, Austin is a tough market to beat.  

We would be able to consistently add capital to our investment portfolio yearly, let's say $10k per year.Some strategies that have peaked my interests are SFH or small multi-family BRRRRs, short term rentals, trade up into large multi-family, rental debt snowball, etc. 

A couple of areas we've come across with more options for multis on Long Island are Lynbrook and Valley Stream.

Simons Island, GA.

Bang for your buck" is hard to say because no matter what system you go with you're going to have to pay and then be very consistent & patient to see any results.

All marketing works if you are consistent. 

I live in Nassau County, Long Island but feel that as a new investor, properties here are very expensive.

In our experience, the higher calibre tenants prefer a longer term (they want to settle down and find a Home); though when the housing market heated up we also had a lot of great applicants who wanted the flexibility to leave if they were able to BUY their own home (a bit more work for you, but not awful if the tenants are consistently good).Congrats on the purchase!

Additionally, networking at real estate meetups and telling people your goals will unlock opportunities you wouldn't imagine if you consistently go and meet people each time.

I feel like my consistency and discipline over the past 5 years is truly what has led me to where I am today.
