If you want to hear all the advantages of San Diego RE you can PM me but suffice to say it has historically produced very good returns and this is verifiable fact (anyone can verify this).However, you do not know whether you plan to stay in San Diego. 

Sally,Most likely a thirty day written notice via email and certified should suffice if you don't have a contract

Is there a need to ask my survey company to create individual surveys for each lots we are looking to sell or one survey for all of it will suffice?

A good umbrella policy should suffice until you start to accumulate more. 

Even an email could suffice, but I'm no lawyer. 

An LLC in the state where you live will probably suffice for now.

Most servicers require an interior valuation ( almost all 1st mortgage investors require this ), but once in awhile an exterior valuation may suffice.

I feel like I could be pretty resilient from investing in the stock market for a few years but I guess I will never know if a bad deal would permanently scare me off or not since I've never owned a home before.Do you think rather than finding an amazing deal it would suffice for now simply to find something that could reduce what I would be spending on rent somewhere and then continue to search for good deals?

For me, when these issues arise, a quick email that they're working on it will suffice and then they can update me as they make progress.

If one was to GC a new construction or a flip project (in NJ) would you need to take out a general contractor insurance policy or does the builders risk insurance policy on each property as well as hiring fully insured sub-contractors suffice?
