Still red hot market in Austin.

I'll live in the carriage house in order to get the homestead exception (already checked out the STR permit and zoning). 

It fits today.That being said you likley don't need to do it all at once if it is outside your comfort zone.

Hello All, Currently, i own a fleet of 65 trucks but I have been leasing inside of a few yards for some time now.The property should be between 7 and 10 acres in a light manufacturing zone or San Antonio.

Find out if the property is in a flood zone, what are the taxes compared to other adjacent neighborhoods, are there HOA, or other monthly or annual fee's. 

Now, I am NOT telling you to go buy in a war zone.

He wants me to be the project manager with a couple commercial properties he's developing because he does not have the time to communicate with the architect, engineer, someone helping with the zoning that has connections to city council and the land development commission.

The piece of information that you've stated, Zoning as R2 for Duplex, is the best item to help answer your questions.

I say "could" because the assessor is likely to use the sale price as the assessed value, but that's not necessarily the case.The NH Department of Revenue Administration has links to information on both Current Use and Timber on their web site, https://www.revenue.nh.gov/mun-prop/property/You also want to check the Zoning Ordinance in the town carefully to see what's allowed in that particular zone. 

I second what @Jay Redding said.
