In any case, once these properties are theirs solely, should they continue to be held in name only but with high insurance polices as they are now?

After moving out, I knew I was responsible for some damages my teenaged daughter had done,and at the time I called the police when the damages occurred AND also let the landlord know that they had happened and I would be responsible for the cost to repair,I even hired a company to do the repairs just after I had moved but they let me down by taking a bigger paying job.So I informed the landlord to hire tradesmen to do the repairs.Then I begand getting bills for damages that I was resonsible AND DAMAGES THAT HAD NOT HAPPENED WHEN WE LIVED THERE, but he has taken photos of these damages.Now I must assume he himself did these damages I would guess in order to have me upgrade/renovate parts of the home that he does not want to pay for, yet wants to improve.How can I prove those damages were never there when we lived there, and that despite he has photos, they do not reflect anything that occurred during my tenancy.Also I moved back in april, and have made all payments ,yet he continues to send me bills.How long after I have left can he continue to send me bills?

Police are there all the time.

I’ve talked to a few police officers.

There are no leases...a valid credit card is needed and police remove the rare squatter from commercial properties (just like a hotel). 

Is it necessary to file a police report?

A lot of changes are happening in various areas of the city, the police are patrolling more, neighbors are forming task force to reduce crime, business are moving in & increasing property values.You need to remember, some people live in these areas because that is where they grew up, that is where they feel comfortable with, they have family there, their roots are there,  A lot of these areas have really good people living there who are trying to get by.

I'm a full time police officer living in a triplex.

BUT....when it is time to renew and if you are not an absolute polished diamond of perfection with a portfolio they are still excited to lend against, your loans might not get renewed.  

Rents are a little low for the area but as for location....it is downtown across from the police station and courthouse and about 2 miles away from the college.
