But before we get this news, the tenants crawl in the attic and call the city inspector and they give us a notice.

Quote from @Marc Shin: Look underneath it (crawl space, basement).

[crawling into my office closet while alternating between sobbing and laughing] 

It’s taking Seller a while to provide the HVAC report but while time passes after due diligence - Flooring cost is way too expensive at the price point they’re asking for 130K + Care of property never took place till decided to sell so I’m not comfortable any longer - Home sits on corner lot on a slight hill with crawl space - Lots of weather changes has caused the home to settle + improper supports needed. 

I will say, however, that reading threads on any web site will not take the place of experience.

I'm a web developer/ real estate investor and I just started playing with Dapps, is anyone else working on similar application?

So be careful and make sure you interview the Expediter and that they have had success in obtaining the Letter of No Objection.As far as evidence that you need to gather, look up your buildings TAX Class.You will find it here: Building Information SearchHere you will see something that looks like this:NOTE that while this is a Dept of Buildings Web Portal, what I have circled in RED is the Department of FINANCE Building Classification.You may not have a CofO, but the Dept of Finance maybe taxing you as a 2 Family.

All I am asking is a reference to a bank that has a good web site that will allow me to do all my online transactions and be easy to work with.

Just a side note.. houses in Cupertino that were built in the 50s and 60s many times had NO insulation they just put in two furnaces :) And as you noted they sold for 15 to 25k.. in those days I still remember late 60s when they were crawling up to the 50k mark..

I would suggest anyone considering web developer to build a site to take this crucial factor into consideration.
