@Steve S. and @Jim K. may come across as a little harsh but they make some very good points.

I personally have spent more than 25 years in the petrochemical industry and have had to wear fresh air respirators and full chemical suits in numerous pressure vessels and towers that have had toxic or inert atmospheres that were considered IDLH "Immediately Dangerous to Life and Health", and I still don't have the time nor the desire to worry about how someone's hair or lack thereof would impact whether or not I could work for or with them.

The house is in Upstate New York so we gave her a harsh Winters .

Historically this has proved very reliable long term but especially the property prices have experienced short periods of depreciation (virtually always less than 5 years) and longer periods of stagnation.I make no claim as to continuing property appreciation as I could make a decent case for the RE market entering a period of stagnation, the market continuing to appreciate, or the market to depreciate some.However, I am still confident of rent appreciation in my purchase area (San Diego) for at least the next few years: 1) rents lag property appreciation. 2) vacancy rate is real low. 3) cost to add more than ADU is high - it costs around $100K to break ground for residential in San Diego (permits, surveys, etc.). 4) Minimum wage increases already approved. 5) one of the best weather climates in the US. 6) rising population: one recent study had San Diego as 13 highest population increase of large US cities. 7) geographically constrained: Constrained by Mexico to the South, Pacific to the West, Camp Pendleton to the North, and the East quickly gets harsh. 8) good and varied employment: Hard to imagine an employment category melt down that could impact the range of employment in San Diego. 9) environmentally diverse from mountains to desert to beach to happening urban center.Last weekend I sent out 2 rent increase notices.

If you aren't shoving hot grease down your drains and/or toxic chemicals and/or sanitary napkins, you can go for years without having to have a tank pumped.

It seems that Vinyl floors are highly toxic since they are made of PVC, Laminate flooring also toxic since they have formaldehyde and carpets are also toxic since they have fire retardants and stain resistant chemicals.

And Septic is not a big deal as long as it is maintained (you/your tenants must never put any bleach or chemicals down the toilets, tub or sinks). 

Other than that, you can't plan your entire investment around the convenience of one family (sorry if that sounds harsh).You're in the right place to get all the info you need to make the most of the opportunities you have in front of you.

Most of this is coming from the northeast where people want to escape the harsh winters and high property taxes.

Maybe a 15% if its a really harsh correction but I would say, like others, a 10% drop everywhere is probably going to be the most.
