You can learn by reading some books or wait until life hits you with a problem and then try to solve it.I recommend you buy "Every Landlord's Legal Guide" by NOLO.

I'll be around this weekend if you want to meetup and talk in person while you pass through. 

I actually have done personally exactly what you're describing - HELOC on primary residence, use that to purchase new primary, move into new primary and rent the previous home(4 times in 5 years).

The VA loan assumption can be done by a non-va buyer, as long as that person selling does not use their VA loan benefits on their next purchase.

But I raise it incrementally and give them a respectful notice in person.

If you're going to manage a GC, make sure to meet them in person and avoid paying for the entire job upfront (typically for smaller jobs, you will pay half upfront, and half at the end). 

Thank god I did because I received it on the last day I could go to the assessor and talk to her in person before I the may 28th appeals datethe letter reads that my new assessment is 590k and that my new taxable rate was 91% of that 590k.  

however for one living in CA I do like Vegas personally ( I have invested there) as I have invested in over 20 states.. what I like about Vegas is the age of the homes you would buy at 500 to 1 mil.. no really nasty weather that adds to differed maintenance..

If it is under $100K, it is going to be hard for a person to get a mortgage. 

The person being interviewed had a marketing strategy using TV commercials (maybe billboards?)
