But it looks like SLC is pretty strict/ does not allow them in residential neighborhoods? 

one of my clients that has a pretty big PM company.. had a unique way of doing this.He offered 50% of the first months rent or 500.00 minimum.. he would have 4 or 5 agents at the weekly meeting handout the list of vacants .. each of them would go place a sign in the yard and first come first served.. he found that potential tenants would call the first sign if no answer they called the next one until finally someone answered.. it worked pretty awesome for him. 

Pretty reasonable when you think about it. 

The risk/reward here sounds pretty far skewed.

I live pretty central in Houston, on the train line and my home have a full renovated Garage apartment that has been listed on the popular platforms. 

that's a pretty intensive list more than most home inspector bring 

I have been getting a lot of interest and inquiries pretty quickly into my rental. 

The renter has been pretty great generally for over a year.

It is usually difficult to take money against it from the bank, it might not be a 1:1 value add - meaning if you invest 100k into an adu it might not raise your value by 100kThat being said, it can be pretty lucrative especially in expensive and sunny CA - since building lots are no where to be found and existing real estate returns are very poor.My partner builds these units.

If you don’t want to spend money I’m pretty sure you could get someone to grade the surrounding dirt and add some gutters for your $5k discount and gain you will have added value and come out ahead.
