They are doing well with only about 4-5 bodies and just renegotiated the lease for 2 more years starting August 1st at $5k/month.

@Greg Atwood Have you physically put eyes on it and seen the neighborhood surrounding as well?

Some say that it is just a formula used to calculate depreciation, it has nothing to do with the actual physical life predicted of the house.  

Any body else want to share their "Why"?

But we have a need to address not only physical needs, but psychological needs as well.

@Dustin Dummer Issues: 1) Is she sick physically and moving into assisted living?

There is a governing body you potentially would have to answer to that will hold you to a higher standard, but that shouldn't be an issue unless you're doing something sketchy. 

Everyone  knows about physical vacancy, but many new landlords forget to consider the more insidious problem of "economic vacancy".

 Tenants typically assume you have an HVAC repair person (or ANY repair person) safely stored up a body orifice ready to be pulled out to address a repair the minute they call (which, by the way, is typically one minute AFTER the HVAC repair company shuts down for the weekend....in which case the tenant will tell you they have been without air for the past two days but have only now managed to figure out how to dial your number to tell you this).   

bust  that was more minor.... then the grand daddy of them all 08 GFC... were much bigger and capable investors than myself lost it all... was a sad time really.in GA 450 banks went under... those mainly local community banks owned by the locals.. sad deal those things. but here we are and things are good again so its make Hay whilst the sun shines.. but like I tell most folks RE to me is not a job its a lifestyle... and retirement is something I will do when I can no long function either physically or mentally  :)  I have no desire to be retired.. or stop investing or working.I really dig what I do.. almost all my business partners and vendors are late 20S to early 40S I just love seeing them take off and being able to help them with their business's...
