Get financially healthy.

Keep her healthy, happy, and working as long as she can. 

Although, still not sure about the split.I already have: - healthy 401k and I contribute the max- roth IRA- I own my primary residence (have a mortgage) - I own one rental property (with a mortgage), which is cash flow positive- I also have $30k in savingsMy plan is to continue saving and start buying other rentals.

I'm exclusively using the Fannie mae Healthy Housing rewards now to remodel any affordable housing as removing lead and asbestos is a big profit center now.

However, you could try to somehow convince the "healthy" tenants to mow the grass or in the very least, hire a landscaper to mow the grass. 

I agree in principle as well; there just needs to be a healthy dose of common sense in the process.

I sold the property two years later and used the proceeds from a healthy appreciation to buy lots in a hotter market - Cape Coral.

Message me, I always like a healthy debate.

I have intentionally built a healthy owner-tenant relationship over time, and I find that based on the mutual trust component, she cares for the property better than any other tenant I have had. 

Also, different points of view and different objectives make for a healthy market (and an interesting discussion).
