This is dangerous territory because you are talking about your family.

Quote from @David Kanarek: DANGER !!!

Lending to those who can’t even afford a down payment, unsecured, or in second-position at best, is about as dangerous as it gets.

"The most dangerous moment comes with victory."  

The IRS is concerned with the tax return that is reporting the activity of the property. 

I mean one of these posters was told their "turnkey" property had dangerous sidewalk conditions questioning how "turnkey" the property was and their response was the tenant's don't care about the sidewalks.

In general, if I personally don't like something, it's less of a cause for concern than if a good tenant doesn't like it.

However, with the rates and conditions of any triplexes and fourplexes we could find (we did find one, but it's in the Pendleton Heights suburb of KCMO, so we were worried about it being too dangerous of an area), we were wondering if it's worth it to buy a duplex and rent out the other half to help pay the mortgage, or if it's more worthwhile to rent an apartment and try to save up to buy a residential or commercial MFH later?

If you tell the constable that you are concerned about damage, they may talk to him about leaving responsibly.If you are concerned about violence, have a means of defending yourself and let him know it.

Under Alabama law, that is a VERY dangerous play and you could end by losing money.You also cannot sit back and let him build the house and say "Thanks."
