You will be house hacking, so ask yourself "Is this somewhere I would like to live?" 

When I was going through the mortgage property the loan processor (didn't really seem like he knew what he was talking about fully) mentioned I can't put the house in an LLC because its an FHA and it might make the loan Due on Sale?

I've already closed on the house and currently have an LLC in CT but have not moved the property over to the LLC yet because I wasn't sure if it makes better tax sense to move it under an LLC where I live (CA) or an LLC where the property is located (CT)... any help you can provide is much appreciated! 

I'm a licensed builder and have been actively building and renovating homes as my primary occupation while dabbling in the RE space buying properties, fixing them up and flipping/holding.

I want to buy a new private home and use my current primary residence equity (plus some cash) to buy a new primary house cash and then sell the old one.So, I am looking for a HELOC with little to no closing costs, as I will retain the money only for as long as I am selling my old house after buying a new one.Any advice?

I have a house that I am renting to my sisters family.

Very different answers to your question depending on the answer to this one.If for a career path, I would agree with @Michael K Gallagher and find a brokerage that is actively doing deals, has a property management division in house, and has brokers covering each of the key market segments - multi-family, retail, office, industrial and land.

If you google Larry Higgins Skip Tracing or Larry Higgins vacant houses, you’ll find podcasts I’ve done on the topic of utilizing Skip tracing for deals.  

Secondly is this currently rented by the room or rented as one whole house?

And I bought 10 houses in Arkansas in the last year without knowing anyone in that town.
