Are there any general contractors or others that have recently built that could ballpark the cost to build per square foot for me??

You already have your foot in the door, even if you have fallen behind. 

Ballpark cost regarding pavement itself (it depends on the design, your unique market, but for parking lots, assuming no big trucks or lots of scholar buses):Compacted subgrade (at 95% compaction modified Proctor): $3/Suqare YardAggregate base course: 6" @ $7/Square YardAsphalt: 3": $14/Square YardPavement markings: $1.0 SF -- this usually runs on the lower $0.5 to 0.75/SF, but your project is so small, companies will charge you more.  

Some of Berlin's most attractive feature are: Relatively low rents (compared to Paris, London, Brussels, Madrid)Low real estate prices (idem)Comparatively low living costsAmple supply of parks, lakesCultural amenity: Museum, squares, historical sites, churches, etc.

Then, when the deal is found, you already have a foot in the door.

Found this document on the city website. http://docs.sandiego.gov/municode/MuniCodeChapter1...It says "RS-1-7 requires minimum 5,000-square-foot lots"

I recently watched a bigger pockets Youtube video the other day, i forgot the title but its about the 4 square calculating a rental property.

@Brandon Vannier I spent over a year building my team now I don't have to step foot into the market to close and maintain new property.

Even if the seller told you a number, you always want to measure for yourself to verify the square footage.
