I reached out to every tenant before to warn and ask them to take precautions. 

I would gladly go to an in person meetup with the proper precautions taken. 

I have worked with aluminum wiring and, while there can be issues with it, it's generally not a big deal if you take precautions.

I just got a new investment property,  there is this potential tenant, single parent with four kids, the eldest daughter is 24 yrs old, the tenant was upfront about a rocky credit, but when I ran the application the credit was 420 with student and car loan, there is a bunch of default payment ranging from kohls to rent default from two years back,  although the background check came in clean with no eviction history, I used Cozy app for screening this time, the lady says her eldest daughter has a good credit score and between both their incomes they should be able to meet  the income minimum, a part of me wants to help here but I am new to this so not sure if its a bad mistake to let my emotions take overI was planning of using some precautions like  getting two months deposit, doing a month on month lease, having both applicants in lease contract... what else am I missing, or should I just stay from this.. appreciate your advice 

The property is in north Texas and we took all necessary precautions during the winter storm to turn off the water and drain the lines.

I'm finding conflicting reports online about homeowner removing own asbestos (taking the proper precautions of course).

I work very hard to avoid problems by putting the correct structures and docs and precautions in place upfront.

I've even seen some pier homes built inland that way on low-lying properties as added safety precaution and likely easier than trucking in a ridiculous amount of fill dirt. 

No call backs.Should I leave a letter in their mailbox or their door that I will be terminating the lease at the end of term as precaution measure anyways?

Great advice from "The Millionaire Real Estate Investor" concerning prudence and precaution is along the lines of "I'd rather pass up a good deal than jump into a bad deal."
