If I were the lender to "C" buyer, and "C" buyer is purchasing the property as a primary home, FHA is out because of the 90-day flip seasoning, and Conventional is possible, but again, "B" is not yet reflected on title.

Bulk Sales provision should be in every single NJ contract where the owner is engaged in business and not selling in the regular course of business or a primary residence.

At the same time, real estate has been overlooked by many traditional financial planners, who don't understand it or haven't been trained in it.

They are all in stable neighborhoods composed of primary owner/occupiers in markets with strong 30 year population + job growth forecasts.Sources of risk come from a variety of sources, starting with (1) the market, (2) the property and location, (3) price you pay, (4) management strategy, (5) rental rate you set, (6) rehab budget, (7) service provided to your tenants and how strict you are with them, (8) your ability to attract and retain high quality brokers, leasing agents, inspectors, handyman/contractors/agents, etc, etc., (9) level of investment experience you have, (10) familiarity of the market, etc.As an investor, one of my primary responsibilities is risk management... my ability to fully understand all of the risks that I am taking and put processes/structures in place to minimize or control these risks.And if you are a successful risk manager, i have found that in REI you are able to mitigate the downside and generate returns that ARE NOT commensurate with the risks you are taking and do so by providing a triple win to your investors, your tenants, and yourself!

As @David Chwaszczewski said there's a big difference in mileage/rate for primary resident vs investors.

Is it a primary residence? 

It must be your primary residence but their is no rule saying you can not sleep over at your significant other place occasionally.Every aspect of investing has a measurement of risk ;)

I need recommendation on what are best options for my current primary residence.

Example: I bought a $200k SFH as a primary residence.
