Every six months, while you're there replacing smoke detector batteries ;c) ...

REPAIR/REPLACE SMOKE DETECTORS.

They don't have parties, police activity, they know how to fix simple things that the younger generation either never learned or doesn't care about, and they know that they need to pay their rent.You could tell them that your insuirance company requires you to give the house a yearly "once over" and you could go in and test the smoke detectors, check the furnace filter, etc.

Then put forth a motion to the HOA board that any unit more than 2 months behind on their HOA bill will have the outside of their front door painted bright red and "UNPAID" across the front in bright yelow, and their family name posted on the "Board of Untrustworthiness and Shame" - and online.

I've found some cheap units for $150 that are self install and video record several seconds of footage when the motion sensor is activated.

What I need to invent is a valve for the water main that when the temp goes below 40 degrees automatically turns off the water and at 50 turns it on , and then have auto drains on the low points that open up at 2 psi and close at 10 psi . ( those are available) Have it tied in with an annoying alarm like a smoke detector .

Its actually just a questionnaire and asks things like, "Do you have smoke detectors in each room", etcWhat would this go under?

Some; however, seem fairly simple to fix (CO detector is missing), while others I fear may be more complicated without knowing what the original construction actually was (Remove work performed without permit and restore building or site to original construction.)

If it's in good shape, we turn it over ourselves quickly and move on, charging tenants for any materials that we feel are over and above (like our carbon monoxide detectors were missing, so we charged them for new ones).  

we used the extra blown in insulation to fill in the crawlspace under the kitchen and under the bathroom.I used the foam in a can to seal all the light mounts and smoke detector mounts with firestop and I am happy to say the house is more quiet and the heat pump does not struggle anymore!
