I did notice Waco was coming up on Airdna as a good market for STR's but I was confused as to why, now it makes sense, must be because of the college there

I've noticed investors finding some promising opportunities there despite the current rates, partly because of strong rental demand and growth potential.At the end of the day, it's about aligning with your long-term goals and comfort level.

I also notice a lot of the school systems are not rated that well.

Perhaps their lease term isn't up or maybe they were not given proper notice to end their tenancy.

I noticed you're interested in Cleveland market, I personally love the market because of its cash flow.

What is the best way to give notice and what is a reasonable amount of time?
