I really trusted my agent and knew several people who had invested in Reno so I took the leap after trying and failing for years to buy my own home in really high cost cities where I lived (NYC, DC, SF Bay area). 

There are many licensed inspectors you can hire to do this. 

(Where Footloose was filmed!). 

I wouldn't recommend an ADU and take that money and invest it where you can pull capital out faster. you can do much better.

Everyone's favorite answer in real estate---"it depends".That being said, you have to start somewhere to figure that out.

Besides Zillow and similar websites, where should I look for leads?

I do / done many rent to own (contract for deed) and a few seller finananced deals where I keep the note.Why not in parallel use a flat fee listing on MLS too?   

The other thing I can think of that  they can do is use those in the dryer dry cleaning kits but not sure if you have the kind of tenants that might do that either with work clothes or drapes.

This site has been instrumental in getting me from 0 properties to where I am today. 

Where are you looking to acquire your next property?
