I'd agree with the previous posts and have a contractor or engineer do a quick inspection to make sure the bowed floor joists aren't the symptoms of a larger problem (i.e. sinking foundation).

I think the difficulty is a symptom of market conditions. 

I suppose the only question I'd have is with this size of a house and only a couple would the daughters and granddaughters soon be moving in also.For what it's worth, I've got a tenant couple who are in this late 60's and both have medical problems (he with heart disease, she with significant diabetes). 

Of course, I readily admit that's about as helpful trying to self-diagnose via a symptom search on WebMD.It does seem to my laymen's eye that an STR could, in fact, be thought of as a modern-day boarding house, just with different technology and a remote host.

And the very same symptom causes your family to try to get you into rehab for your addiction.

We would like you to know the following: The resident will be in self-quarantine for the 14-day period and is currently not exhibiting any symptoms.

I couldn't even be in the same room she was keeping the rabbits for more than a few minutes without developing sever allergies & strong asthmatic symptoms.

Or whenever home builders start building again like previous decades in the past to meet the demand. the economic research I am reading indicates millennials are less likely to live with parents after graduation from university compared to prior generations and they are choosing to rent for now to remain mobile. they are not buying homes in significant numbers. that demand is creating all the rent price inflation. recessions do not equal home price deflation. recessions in 1981, 1982, 1991, and 2001 saw very little to no impact on home prices. the Great Recession was only recession caused by housing/lending. prior recessions home price was a symptom not a cause. just before the Great Recession there was a housing shortage. today, the Fed is specifically targeting house price inflation. rather than let all the QE mature and roll off the Fed is selling those assets prior to maturity increasing supply and increasing yields which will push up mortgage interest rates. that could impact buyer demand in some markets. when interest mortgage interest rates hit 5% buyer purchasing power is cut 17% to 21%, but that may not deter buyers with lots of cash reserves. we are seeing all cash sales 25% nationally. we are seeing sales with financing and buyers paying cash for low appraisal differential.
