That looks like a screaming good deal to me on the surface. 

@Roshan K. is exactly right - treat the daughter exactly like you would want to be treated - or to drill down even more, threat her exactly the way you would want YOUR daughter treated in the same situation.In addition to the PR hit you'll take if you enforce the guarantee, you'll have to figure out how to keep your own conscience from screaming bloody murder at you in the middle of the night.

You jump on a deal if the number scream to you this is right.

also avoid (or at least patiently, thoroughly screen) anybody who is in a big hurry to rent,   and run away screaming if they offer to pay multiple months up front in cash or they try to get you to to skip any portion of the screening process, or start in on the sob stories.as for finding people with credit better than 700:https://www.fool.com/the-ascent/credit-cards/articles/heres-what-americans-fico-scores-look-like-how-do/so roughly half of people have credit of 700 or better.   

Him and my other tenants husband got into a screaming match outside the property.

I would say screw them, and do the work, fix the yard while they scream and holler... but that's not the case. 

Coils screams "cheap" and "old".

There is only so much I can do on Friday night when other tenants are texting me saying the upstairs guy is screaming, and the person they are living with can’t do much about it because they have temper.

Guess what, exactly, one week to the same day and nearly the same hour, she called me screaming saying my triplex is on fire.

Have screaming kids or a barking dog?
