As a disabled person, I want to be in real estate, but I know I am limited. 

I personally will try to avoid buying a home under 1000 square feet again.

Sometimes only one person to help you and they're not quick, or not cheap, or you just don't like the way they work? 

I have a 780 credit score and no debt besides my personal residence.

Congratulations on the duplex -My investor clients have acquired several multi-family investment properties locally in the market I operate in Northwest Indiana - Figure out your personal investment objective for the next 4 years and align yourself with the next property that make sense in this current market environment-

Questions they will have is who is the owner, what experience do they have, is their key person insurance against them etc. 

So it's just personal preference and budget for a host.

Account holders can't take any write-offs personally for investments made in the 401k.

Quote from @Jeff Sanders: Personally coming from an agent/investor in CA, I always get a quote from a broker of mine and make sure I am knowledgeable with the fees/costs.

I personally own a property in Windsor Hills Resort, right next door to Disney World, and we absolutely love it.
