Seacoast NH, for example, has some great potential with short-term rental markets (Airbnb, VRBO), especially in towns like Portsmouth or Hampton, but the regulations can be a bit tricky.

I have a basic spreadsheet built for clients that I'm happy to share for free.

It becomes a win-win.On my most recent tenant, I experimented with a built in rent increase.

Additionally, working in a small-town market taught us how to effectively price properties for faster sales without compromising profit.

More and more ADUs are being built.

It could be that the property wasn't built yet and it was a land purchase then the buyer bult the home. $5,000 is still pretty cheap for land though unless the land was bought long ago.

It might have been more when yours was built.

You could also check what Realtors in your market are preferred agents here on BP- they should have at least a little experience with investing and a network built up. 

There has been an influx of out of state investors and in town investors aquiring propertys as of lately.

I'm in a drive to beach market so I'm on it but I would think college towns, mountains etc. might be similar.
