If they have one for your car, find out how much they will charge you to install it.

On one $750 house a new 50 year roof was installed in 2007 and a new gas furnace and central air was installed in 2012. 

You may want to just have those installed so future tenants (and you) don't have this same headache.

Such as missing roofing tiles, sagging ceiling, cracks in the foundation etc.  

Not to rough inside but it does need a new roof  and gutters ASAP and Central heat and air installed.  

@Dawn Anastasi yes the couple provided their midwest landlord who I called and got a raving review but it's a private owner so who knows, in retrospect.And they indicated they were staying at Extended Stay America Pasadena since they flew into CA, which struck a chord with me as months ago when I relocated from NYC, I also stayed in Extended Stay America but the one right near Long Beach Airport, until I closed on this house. in retrospect, i realize when i advertised for a housemate on CList months ago, i had initially indicated i stayed at Extended Stay America and had just closed on my home and was looking for a housemate (and found a great one just weeks ago, who is also from NYC but now works for Los Angeles Fire Department and Los Angeles Police Department thru a government contractor. would not put it past these characters to have actually stalked my CList posts and gathered info to use to sugar-coat their story. anyways i dont wanna get my housemate involved as he's new but at least he has connections as far as some of his clients, if it comes to that for whatever it might be worth if things escalate and/or become violent. i'm a very diplomatic person, not sure if that helps in this sutation though =/they offered to pay more rent ($300 more per month) and of course i said no, you need to work on finding a new place better and fast before time runs out for your situation. and in reply they (well the father, he does most the yapping) just asked me to install area rugs which they initially agreed to install in the first place even before 3 kids magically appeared in the picture and now are claiming the rugs will help deaden the sound but that I have to furnish them. guess there's suddenly a few screws coming lose as the act is finally falling to pieces. i mean who in their right mind is going to cater to their 'needs' after being lied to and my signature forged (God knows where else?!).

depends, I always preferred drywall as opposed to paneling but if the paneling is over plaster and the plaster is in terrible condition removing the plaster and installing new drywall can be a nightmare you may have to rewire and replumb the whole house if you are getting inspections done, so take one room or even one wall at a time, if you feel at that point you can do the rest of the house then go for it, it's also an affordable thing to sub out, you should be able to pay someone $10 per sheet or less to hang and $10 a sheet or less to tape and spackle depending on how many sheets you need done, keep in mind a sheet of drywall cost around $10 a sheet also,  you can also remove the paneling and do a drywall venere which is a thin sheet of drywall over the plaster basically just like paneling except it's drywall.

There's a ton of money to be made, but problems also.I install motion sensor lights on front and back, lock the gate to the backyard, and leave a radio on inside the house.

Tile in all common areas!
