.- buy a vintage Airstream, fix it up and decorate it super hip, and operate as a vacation rental.

The area is vintage late 1970's early 1980's.

Alex  AIrbnb right now is great for the south Florida area but like any thing in real estate it a risk  but I also think it will be great if you had a airbnb manager just like a property  manager . can't say im a newbie because i been learning about real estate for about 2 years ..Having 2 week booked on air bnb is the same as a whole months rent .. and the cleaning services are moving toward the airbnb side on things. plus south Florida will always have the snow birds season (people thats running from the cold)....AS far area in palm beach i think lake worth in some part are gems for airbnb price and location wise .. i just seen a duplex going for 165k of it my need a Work but It in a great area ....  

A vintage 800 sq foot 2 bedroom vs a new rehabbed 1500 sq foot 2 bedroom are going to get very different rents and zilow can't tell the difference 

That said, using GIM in the first place could mistakenly filter out those "unlocking potential" gems!

there is a home just listed in Vegas and there is almost over $80000 difference between zillows zesitmate and redfin,s estimate I guess it depends if your buying or selling https://www.redfin.com/NV/Las-Vegas/6860-Vintage-H...https://www.zillow.com/homes/for_sale/6860-Vintage...

@Chris Fi I am very used to buildings built in the 50's and 60's as I own a lot of that vintage here locally in Berwyn and Cicero, IL.

Growth here didn't go gangbusters, so there is still a short window of opportunity left to pick up the final vintages from the foreclosure crisis. some neighborhoods have already heated up, but to give you an example,i just passed on a deal in an A hood with a golf course that was going to cash flow.

You will find out that the site is a hidden gem.

I've got two of them (purchased through ebay) vintage ones; probably made in the 40's or early 50's.
