No, you won't disqualify yourself in the future for a mortgage on your primary residence if you start buying rentals, especially if you go traditional over FHA.

An example would be a former work colleague who has recently retired with a sizable 401(k) and is looking to roll that money into an IRA and use some of it to fund real estate deals.So here's the tipoff: Most legitimate PLs are not out asking complete strangers if they need a loan! 

Someone asking for seller financing does not excite an agent.....that usually means they can’t qualify for financing and Very few sellers on the MLS are interested in financing the sale, especially if someone doesn’t qualify traditionally. 

They said they are only accepting Schedule C for self employed because the Schedule E does not meet the SBA traditional guidline for an approved business. 

Nearly all the agents I know typically deal in traditional SFRs.I can provide more information, if desired.

Of course, I wouldn’t overlook other traditional sites like Zillow, HotPads, Trulia, etc.

Having a hard money lender will give you an advantage with a cash purchase, and is certainly required for those properties that need a major rehab where traditional financing wont work.Paul

If you are using traditional finance this won't be an option so get with a good realtor. 

@Mark DavidsonWe recommend Solera bank, Solo 401k bank accounts are their specialty, they have a department dedicated to 401k/IRA clients.
