You only want a mom (female), so that's sex based discrimination.

We set up a critter cam to see if we could catch an illegal dumper on film, but it didn't work.We have one tenant who is into ecology.

He does not have the children full time but he does weekends and other random weeks.I was under the impression that when renting, children of the opposite sex could not share a bedroom.

That's great that your parents are willing to help and that you're bold enough to start now while your peers are busy dreaming about cars, sex, or video games.

I've found Notary Cam and Notarize.

Can/should I tell my buyer's agent to show me homes electronically (i.e. via Skype or phone video cam)?

If memory serves correctly, he was negotiating sex in exchange for not collecting rent and operated poorly maintained units. 

If you are talking an older strip center with mom and pop tenants the yield should be higher.You can run the numbers from the profit and loss statements and CAM re-imbusements after base rent and management.

Those lenders do not care about race, sex, national origin, religion, or anything else.

You cannot discriminate against applicants with felonies regardless of what their crime was and I am not sure about sex offenders.We tell applicants to drive by the property and see if they like the looks of the building and neighborhood.
