Any advice for finding / approaching owners for off market deals? 

@Robert QuirozThe landscape has changed in all markets and the days of easy BRRRRs, 1% rule, 5% down, low rates, and strong appreciation are over.

My market has a low vacancy rate.

You will most likely pay more than market rate so take that into account.You will then have to get it all furnished which can cost a pretty penny.

Should we buy and market for S8 tenant or without ?

However, availability remains tight, with a record-low vacancy rate of 4.5%.Retail move-ins reached 86.3 million square feet, while move-outs balanced the market at 86 million square feet.

And how does one even market the space if you do not even own it yet? 

Hello Friends, What websites and criteria do you'll use to find new markets?

I’ve been keeping an eye on the short-term rental market here in Indianapolis, and it’s definitely heating up!

You will get less than market because they are occupied.
