Bathtub is black, fridge disgusting, etc.I outlined clearly what was expected, and they didn't follow it.

Items such as controlling the flooring on the inside of the unit (premise is noise abatement so some associations do not allow LVP), limiting rentals all together (premise owners take better care of the units), limiting certain bathtubs (premise: Common water heater and large jetted tubs use more water), limiting STRs (premise: they do not want strangers having unabated access), no washer/dryer in unit (premise they may leak resulting in damage to other units), etc. 

You can keep the design and finishes extremely simple and rent proof, yet still quality; simple one pitch roof, standard size windows, LVP floors from the start, off the shelf insert bathtubs, cabinets, etc. 

The house also has a large bathroom downstairs that has a bathtub, tiolet and vanity.

For one price.Kids = loud, messy, more utilities, more people to crowd a place, liability (bath tubs?

(Of course, it's not like I could likely collect the full amount... but so far it's been a deterrent for them to smoke on my property.)Families with kids:- more wear and tear or spills with the kids- liability with kids (stairs, bathtubs, etc.)- perhaps less likely to move as often as roommates- perhaps more likely to be a little more careful and treat the house as their 'family home'- kids are rough on houses- perhaps more established with finances, job, credit (but not enough to buy their own house)- might stay in your house longer, meaning you don't have to do this as often.

Research local insurance/pool guy costs.I think a tenant could try to sue over anything-- swimming pools, stairs, bathtubs, stoves, hot tubs, ANYTHING.

Had they used the regular kind that screws in, all of that sewage would have backed up into the bathtub and I would've gotten a call right away and avoided the entire crawl space fiasco.A couple of funny things happened that day.

But my contractor has advised me that in the great city of Lowell, Massachusetts, any update no matter how small (like putting up new cabinets or updating a bath tub) would prompt the city to make me put in a Sprinkler system.Is there any truth to this?

Looks like it requires a new toilet, new bathtub or surround, prob want to redo the flooring and has a vanity/sink already.
