However, I am worried about the outdated electrical and water systems for safety concerns.

Unfortunately we have discovered that the guests of a couple of tenants were not being upstanding citizens and got themselves in trouble with the law.  

This has been court tested by over 40 years of case law. 

Here’s a step-by-step guide to help you through it:**Understand Local Regulations:**First, you need to check with your local city or county to see if the zoning laws allow for this conversion.

In a cooling climate your state's laws probably state the calendar date upon which heat needs to be provided (for example beginning October 15th) and the temperatures that the unit is required to maintain (for example 65 degrees). 2.

Is there any state law that I can use? 

The law will come down on you hard for that in other places as well.I would think about how much money it is to go lead free if you are buying a new property though.

If you found a replacement tenant that he found suitable and moved them in before you entered in any unpaid portion of your lease, I would expect you to receive a full refund of the security deposit.I would check with the state laws and see how much you can sue him for in small claims court.

You are required by law to find a replacement tenant as quickly as possible and then refund any unused rent income.

The laws need to be changed.
