Also, any best practices for room rentals that you recommend for screening and keeping tenants.

There is much to learn: pricing, marketing, screening, contract law, lease enforcement, late/unpaid rent, property abandonment, squatters, maintenance, tenant neglect or abuse, communication, and 417 other things.Buying a decent property but not managing it well can impact your finances, marriage, sanity, physical health, and desire to invest.

I ended taking over the listing and screening tenants on my own through Zillow.

Screen your tenants well.

Move on and try to screen better next time.

Some of the areas that we invest in have some clauses in their zoning forbidding more than 3 individuals unrelated by blood or marriage from occupying the same unit. 

It seems like there should be a dividing line somewhere to make it easy, but also maybe not because both of these ladies seem to have pretty solid claims although I would think the last one has a better shot.From a legal POV (although this is not legal advice although I am an attorney), without a will the estate gets probated along blood lines.

If you screen your tenants well you'll rarely even need to know any of this.

To answer the title of your post, selling fsbo can be a good idea if:- you have experience selling RE- you price the home to sell- you have systems in place to collect inquiries and facilitate showings i.e. call center/email/google forms for screening inquiries, showing agent, lockbox, security alarm, etc. - you have dozens of local agents who can market the property for you and bring you a buyer- you are listing in a desirable area with low-inventory - you are not in a rush to sell

From my point of view for event guest screening and security deposits, Superhog is reliable and integrates well for STRs and events, but you might need to adjust its setup for your use case.
