After your friend has done some emergency "damage control" and he's got the dryers/fans going, he will want to call his agent.

Remember you don't have to own a property to control it.

The landlord is concerned about maintaining some control over the quality of the tenants in his park and you should sit down with him or her and discuss the parameters that would make him/her happy.

for the past couple months while working on my fixer, on the sidelines had been dealing with alot of stray cats on the property (its a huge lot for the area) and 'catching' the feral cats and taking them to the shelter to be spayed/neutered, vaccinated then released and wished they were closer and so wonder why not get a shelter started in my city since theres none not even 1 that i could find after looking all over. heck even animal control is outsourced to the surrrounding city (long beach) and county (los angeles). of course wouldnt do it from my residence, so will need to start building credit up for occasionally ordering supplies and services (ie vaccines) for rescues in the future shelter, if this city allows for such. as for securing the shelter location i doubt i'd use mortgage or loan as i've so far always done fine enuf buying properties cash and somehow making ends meet, however barely.right now i dont even have a taxpayer EID. do non-profits need one?

Ideally I would try to buy out the smaller parcels so that this becomes a non-issue and so that I can have some control over the future use of the homes/residents.

. ~$62K gross rents w/ $10K gross rents upside w/ rehab (but under rent control).

I believe that can happen even in rent control areas (although I could be wrong on that since I avoid areas with rent control).

It's your property and you have complete control over it, unless he was an equity partner or gave /loaned you money for the property. 

There is no way to control this or know in advance if it will happen.

Where can I call to check if a property is under rent control?
