Question: When buying an old building (constructed in 1900 with an effective build year of 1960), what should I look out for and ask about? 

So those were all on my Fico.. my Bank loans from my commercial banks dont show up IE: development loans  vertical construction loans..

I only hold decent properties in nice areas, modern construction, etc.

I have been in the construction industry, mostly residential renovating, so I know how to spot damages, repairs, and/or things that need to be replaced.

I was interested getting information on the cost of building a new house in Riverside county or San Bernardino County. My Name is Sergio your input is greatly appreciated.

Having a tangible property to discuss often leads to a much more constructive discussion.

My background really comes more from construction and development in residential and retail construction.

What caused the issues is that I went into a deal with a partner and he corrupted the deal, my first new construction build. 

I think their general stance is going to be to go with whichever comparable property has the greatest degree of similarity in terms of (probably, in this order): location, age built, quality of construction/current condition, and square footage.

New construction, negotiated price.
