A decision to attempt to go short on a current mortgage with a solvent borrower is a more delicate situation, especially if they have other assets, are high income earbners, or  have substantial funds in the bank. 

It happens sometimes, and it's important to handle this delicately.

I agree, approaching the family and relatives is a delicate subject.I would do more research, go to the city/county and see if you can pull probate records and find out who the executor is.

However, if these are great long-term tenants then I would be delicate in how I approach the situation.

I prefer to remove the weeds manually and then use thick landscaping fabric, mulch and pre-emegent products such as Preen, as mentioned by @Steve Babiak.

What they have is paving fabric , it is but down prior to repaving a badly cracked road , it works similar to drywall tape , it doesnt allow reflective cracking , or the old crack to reappear thru the new asphalt.  

Also, the tenant is a trouble maker, accusing his neighbor's dog biting his kids (which I know it was fabricated) and looked to get insurance payout.Would like to hear some ideas and your past experiences.

I would be concerned about dust, lice, and smells with fabric, although we do put up fabric panels in place of closet doors in some units.

We're blocked on some railings being fabricated and the front stone work needed to be reworked some.

Best to gather your toys and go home.That was my last profit sharing arrangement from a lending position involved.Since then I had several successful deals, one very successful in a steel fabrication business, a grocery store and several smaller deals.
