I agree with being civil about it but if they think they can take an inch, they'll take 10 miles.I especially love Nicole's strategy to always start eviction immediately but to also let them know in the notification that it can be undone if they pay up right away (because if they think they are definitely being evicted, sometimes they will just throw their hands up in the air, give up and not even try or they will get mad and wreck your place).

Only about $1k to $1.5K to replace the air handler.

Having a job takes the pressure off as well.Why don't you be like your friends with stable job and great credit and then you do not have to rely on anyone.

Sometimes it feels good to air it out.

Pipes, pumps, valves, exchangers, reactors, pressure vessels, everything. 

This is moving faster than I had anticipated and I'm worried my grandparents will be pressured into selling their home for much less than it's worth.

Make sure that clean includes cleaning the air ducts if it has a forced air system!

(IMHO it seems like lead paint is only a danger if you're doing activities that lead to paint particles in the air - .e.g, wall demolition, etc.)

If the air filter is dirty it can restrict airflow causing it to "run slow".

Replacing 6 patio doors he disturbed and released asbestos to the air- he also did repairs to the ceiling which contains asbestos in the popcorn- the air test (as well as samples of the drywall and the ceiling) have been made and it is positive, all of them contain asbestosBasically this will increase the cost of renovation quite a bit.
