.,. then Baltimore gas and electric showed up and said their gas leak detector detected small amount of gas leaking.. it was coming from a cracked head on the furnace.. so it was old and need of replacement.. so we decided to replace it completely  however I need to mention I have brought my mother in law on board to do the book keeping duties and she is on site 2 days a week to let the exterminator in and do paperwork.. she was bombarded by this tenant who was threatening to call the police due to no ac and without consulting me she hired someone who was willing to install a unit in 2 days time instead of a week and instead of spending $3,500 for a new unit she spend $7,000.. this is a huge problem for me as I have a policy of no work or repairs done over $500 without my consent.. so he got a new $7,000 unit.. and I have taken the checkbook from my mother in law..

By law, rules have to be in a separate document, but can be changed from time to time without the tenant's consent.

Sending them signed consent forms, etc...

I use a third party service that gets applicants consent by email to run their report which is sent to me.Open houses can be a mess because if you have 30 people show up, it is difficult to monitor everyone and what they're doing while you're showing the property.

If nothing else, you will have a judgement that can be noted on their credit history.Something you might consider for the future: in the form we use to gain consent from an applicant to pull their credit history there is wording which also gathers their consent to report payment events (both adverse and positive) to the credit agency (this wording comes from the agency itself and is part of a template we are to use as part of the service).  

We draw the line on storing liquids such as {lamp} alcohol, kerosene or gasoline in the living space {if there is a garage and the liquids are properly stored in approved containers, that is fine}.If you are signing a single lease with the group of tenants you can require they furnish you with have proof of renters insurance and that you are a named insured on the policy ... you can also require their consent for you to contact the insurance provided to verify coverage.Let them work out whether they purchase individual policies or a collective policy - there's a good chance they will not be able to purchase a collective policy - or that it would be cost effective. 

Swimming Pools, Trampolines and FirePits may not be set up or used on the premises without prior written consent ofLandlord. 

If the applicant meets my qualifications in these areas, then I would request the consent and  fee to run the check via SmartMoves.
