They just reported that the ceiling in the living room is leaking below the upstairs bathroom.

Purchase price: $800,000 Cash invested: $160,000 Stunning turn-key townhome featuring floor-to-ceiling windows that bathe the entire space in natural light.

There is water damage in the main room caused by water leaking through the ceiling.

Other costs to think of are running services (water, sewer and electricity) to the ADU.You can sound proof the garage ceiling. 

They would have taken pics even if it was garbage or holesin the ceiling.

I dont have a crystal ball but I suspect there is a ceiling as wages are not going up as fast and for renters they are generally on pretty tight budgets could be that rents plateau to the mean and what folks can reasonably qualify for IE the 3X income which most landlords use.

I don’t have any fancy pdf for you but here’s a short list:- Look under all sinks for leaks- Look in every corner (ceilings and floors) for any sign of water damage or cracking- Look at the water heater, HVAC, AC, etc…- Pull out floor vents if you want to see what kind of floors are under the carpets.- Look in the crawl space and attic if you can (always have a pocket flashlight on you)The more you can find out on the first visit, the better off you’ll be.
