Not to mention they are fun and informal and can be a great way to gauge if they are someone you would want to follow in the first place. hope that helps and best of luck on your journey!

Plus, I can do hml when I'm a 100, engineers start getting (sometimes nasty) pressure to leave around 50 because they make too much.

Time (and their life events) typically will put pressure on them to lower the price and thus sell.  

Any area that has a huge swath of ESA abusers will eventually see an upward pressure on rents anyway.

This will put downward pressure on rents, and asset values (upwards pressure on cap rates). 

It will require more maintenance for sure as well as possible emergency pump outs which can disturb your guests.Do you currently have an alarm or gauge on the tank to see what the level is?

I have limited knowledge of STR (only 2 months in, and its performing beyond my expectations) and just wanted to gauge value in all directions to ensure I am maximizing my earnings, if that makes any sense. 

Stop on by, meet the owners, and gauge their interest. 

What kind of backflow prevention would prevent this amount of pressure, and why should an owner have to pay to shield his foundation from this "Toxic Waste".It seems like the city should not be maintaining a "Public Nuisance" of "Toxic Waste" that bursts through foundations.It seems like the city should remedy this immediately and also pay for damages to the building.Retrofitting one way waste vales between the units might also be a positive to prevent inter-unit backups like this (on your own dime).But the city should not be blasting toxic waste through foundations--(how much pressure that must be).Toxic waste = AIDS and other similar....Did any other building owners on the street get hit this hard--maybe group together and get this solved.Good Luck with this.

Most of the time, the off-market deals are completed due to some constraint of the owner's situation that pressures the timeline of having to close, such as divorce, death, or liquidity concerns.
