in my mind if your just talking 1 to 4 units  those should be able to be vetted in your head or on the back of a napkin in about 30 seconds..

@Richard Benjamin Wilhite, A great place to start would be the county appraiser records. 

I'm happy to rent in a C-class area, even though it can take some work to stabilize a property.

Anyone who managed to do this probably did it 5+ years ago when the market was very, very different.If you borrow $200,000 to build an ADU, I suspect you would need to rent it for $5,000 or more to make the numbers work.

Here is to a great 2025!

Feel free to reach out if you have any questions.

You will want enough return for the deal to support itself or you won't be able to scale well.

Now if your thinking location jumps out as a big factor to all this, you hit the nail on the head, location location LOCATION. 

1) Yes you have to disclose.

Is there a better way to find out how many existing units are there in each town, or do I need to drive to each facility and ask?
