Best practice is to connect with good property managers like @Kyle Tom from Elite Property Management. 

He said, “We don’t know how to run a mobile home/RV park, we’ve never done something like that before.

@Jason Frink, this page seems to cover it:https://www.omglawfirm.com/arkansas-probate-intestate-succes...Here is a pertinent snippet from that page:If you don’t have a Will, the default order of descent goes like this: (1) full blood and adopted children of the decedent, subject to any dower, curtesy, and homestead interest of a spouse; (2) if no full blood or adopted children, then everything to a spouse of greater than three years or half of everything plus dower, curtesy, and homestead to a spouse of less than three years and the other half of everything to other heirs (per this table); (3) to the decedent’s parents or surviving siblings; (4) to the decedent’s grandparents or surviving aunts, uncles, cousins, etc.; (5) to the decedent’s great-grandparents or surviving great aunts, great uncles, etc.; (6) if none of those intermediate descendents are alive the remaining half can go to the spouse of less than three years or to a predeceased spouse’s heirs; (7) finally, if none of these apply, all the property escheats to the county where the decedent died.A good way to visualize the order is to imagine the following scenario: Alfred dies without a Will.

I would like to get into seller financing and subject to deals but don't really fully understand the payments portion of it.

Yes, I feel that directly owned single-family rentals are really a business and not a passive investment.There are a lot of things that can be done to automate it like taking rent over the Internet, using Zillow and other apps to bring in new potential renters, etcBut others require manual labor.

We would like something that can compute CAM and taxes, etc.

We have no say in matters like these.

In my opinion, this is much more effective than texting, which often feels like a constant game of cat and mouse with phone carriers.

I remember when I was starting out, deal analysis felt like trying to solve a complex puzzle without all the pieces.

Since refinancing and investment income (like rental income) usually aren’t seen as earned income, it likely won’t affect your mom’s survivors' benefits.However, if your mom’s survivors' benefits are based on disability (SSDI), then additional financial or property assets could trigger a review, so you might want to consult a CPA or financial advisor to be sure there are no unintended consequences.This isn't legal advice.
