Is it to soon to start advertising it?

I've even offered through agent advertised properties, but you'll usually get better response from FSBO. 

Advertise that you are holding an open house on a specific date and time.

It is too early for me to state if this will be a decent investment, but the projected annual return was advertised at 14% to 21%.  

We put our place on Facebook and whoever rent redi advertise through.

It may be a better use of your time to begin advertising this unit so that you can get a new tenant moved in as quickly as possible following your current tenants move out.

I'm not talking about a location based on tourism where zoning allows for STRs, hotels and they have existed there for decades.I'm talking about residential zoned areas.

I understand that you want to look for a place with year round tourism, growing tourism stats, favorable STR regulations, etc.

There are lots of ways to find properties:- Buy stuff that's listed on the MLS- Auctions- Direct mail marketing- Advertising- Knock on doors and talk to potential sellers- Facebook advertising- Craigslist "For Sale"- Etc...I spend an entire chapter talking about acquisition strategies in "The Book on Flipping Houses" -- check it out for more details...

Its too bad newbies see this site as a way to find "good vendors" when all it is is free advertising for them.
