To get my local data I need to talk to my Realtor.All RE is very local, not just to the zip code and neighborhood, but when you boil it all the way down it's the individual property because each property is unique in itself.

County liens stay as well such as code enforcement liens.

The inspector said they were grandfathered in vs. newer codes. 

Would be a real shame if you an upstanding citizen looking out for his community noticed code violations and informed the city.....

. ;-)If I HAD to find a deal though, I'd probably pick up the phone and start calling into the zip code I wanted to buy and I wouldn't stop until I had a couple of possibilities, because a bunch always "fall out" for various reasons in the process.

Would you recommend using home advisor's estimate costs tailored to the specific zip code I'm working in to ascertain costs?

Agree, I like to use laptop with excel sheet.

I send my self a email with a blank application as attachment, so I have it on my phone and laptop ..

Put on the key code type locks otherwise your going to end up with so many keys your going to go crazy.. you keep the master code the same to all locks and then program their code.. expensive first time around but you'll love it in the end..Same for entry door,,, code lock and change code if someone moves out.

I have somebody locally that would like to take a look at my apartments to ensure they are to code for an upcoming relocation.
