I was hit by an 18 wheeler 2 years ago - my fault- and tried to start a business last summer that didn't succeed, which it shouldn't have, being that I hated every minute of mobile detailing, and I recently got to where I am at least head above water, but I am paycheck to paycheck.

Everyone else has mentioned the noise but I'd also be worried about water leaking from the top unit into the bottom unit.

If you're attorney is smart and honest with you. ( that's funny).A couple letters showing scare them out.I  have other ways but won't say because everyone will get mad but tenant will leave quickly. ( stop paying water bill).

Equity REITs (not mortgage REITS) are truly great though and have returned 1.5-2.0% more than SP500 over last 20/25/50 years in multiple retrospective studies, and are a great value purchase right now due to being beaten down by fast FED rate rise last 2 yrs, however to get best tax benefits, buy them only within a tax advantaged account like 401k/IRA etc as the big dividends are taxed very high at earned income rates.Good luck, wishing you and wife all the best on your investing journey :)               ps don't ever keep cash at a bank, park in your brokerage account and buy USFR, a wisdom tree ETF, pays 5.39% interest, holds only 8 week US treasury floating rate notes, so you don't need to worry about FDIC or SPIC insurance as only way US govt doesn't pay is if we get nuked, then you won't much care about cash yields, just non-radioactive water. 

For example like clogged toilets or sinks so they don’t overflow and cause water damage.
