You can use Airdna & other STR estimator tools to get data on potential income/vacancy based on your location and property size. 

I had some luck in real estate groups and by sharing success stories, but the pace was slower compared to paid ads or SEO methods.One thing I recently explored was incorporating tools like those for Social Media Posts using AI.

I just sold a rental property which had quite a bit of equity from appreciation and principal pay down through the years.

They sold and the next owner started phasing out Section 8. 

Did not know about tools on how screan tenants.

I say that but my goal for sfh rentals here in illinois was to get to 20 houses in 10 years and I ended up getting to 83 in 15 years (I've since sold half though so I don't own that many now). 

Don't exactly use the price Rentfinder.ai gives you, but use the comparable tools they have and the other prices listed.

On the market as we speak to be sold.

Make sure you are sold on the particular project to get a level of comfort.Past projects might have been A to B areas where upside was greater and risk was lower.

They are one of my favorite tools.
