let professional manage or you should be professional.

Rental property is a business and there are regulation and law. Landlord should familar what to do in such siduation. What should do when sign lease. In my state, we use standard lease that stated the property is "as is" . repair request should based on functional not work. and unless some repaires, most repair the tenant need to pay co-pay (like $60). 

 

Our state law do require when tenant move in, in 7 days, landlord need to exchange all ext locks and check all smoke detectors. 

 

If landlord have all this prepared.no worry. follow the leaee contract.
