@Drew Dahlbergyes you are able to house hack as your primary residence and also put the prop in your personal name 

Are you buying a primary that you will house hack, or is this a true investment property?

TRUST ME, the girlfriend will admit that he was living there and will likely even allow him back into the property against orders.But even if not, if he was residing there, with landlord permission or not, lease or not, he is a TENANT, or at the very least an authorized occupant, and as such cannot be prevented from entering his primary dwelling...not by the landlord.

I currently have a FHA loan on one of my Rentals  ( I lived in the property for 1 year and am now renting it out )Can I now use another FHA loan to purchase another Primary Residence ?

My primary business is selling land in LA and the Inland Empire to homebuilders and other kinds of developers. 

in 20, double or triple that by the time my wife and primary breadwinner retires.

I am currently 24 years old.Here’s a little information on my current property (primary residence):Purchase Price: $130,000.00 Mortgage Balance: $99,937.34 Market Value: $180,000.00Market Location: Spring Hill, Florida, USA (Tampa Bay Area)Of course, the best scenario would probably be to move back with my parents, but, truthfully, I do not want to move back with my parents and siblings; however, I would be debt free and generating income from my primary employment.I feel that the downsides to selling my home is that the market in my area (currently a seller’s market) is extremely hot and, by holding onto the property, there is a likelihood that the value of the property will eventually increase substantially over the next few years.If you were in my position, what would you do?

We also have a primary home with over $100k equity (5 years in possession) and are considering selling one or both to house hack a multi family and eliminate or significantly reduce mortgage.

@Randy Dickerhoff Your primary will definitely factor into the debt to income ratio.

I owe about $68k on it and believe it could sell for about $150k as is based on recent comps.Prop C: Single family, my primary residence in the Overbrook Farms neighborhood of West Philadelphia.
