When I appraised notes for the State of Missouri, the very first question I had was "Is this obligation enforceable, was it in compliance with rules, regulations and laws at the time it was originated?

My wife and I currently own two identical condos (3 bedroom/2 bath) in the same community.

If you claim it as your personal residence, don't also go and try to claim bonus deprecation against it would be my rule of thumb 

Your total rent is $2,500 on a $500,000 purchase price which would be 1/2 percent rule.

From there, I would like to explore house hacking/the BRRR strategy, but I know there are rules, regulations, and connections I will need to make all this happen.If anyone is willing to have a conversation or thinks they could use my help in bettering their real estate business in return for some advice, I would love to at the very least create some new relationships.Here is my 2.6 cents adjusted for inflation...What about getting a realtor license?

New neighborhoods can be brutal on investors with rules. 

Thanks for any help’ Yes we're licensed there and FHA guides in one state apply to all states unless a state has a specific law that supercedes the FHA lending guideline.FHA is always 3.5% down minimum (in some cases less because you're using a DPA or down payment assistance program or 2nd lender to put down over all a lower down payment than 3.5%, Aka for instance 3.5% DPA + 96.5% FHA = 100% financing but just dont kid yourself this is fully 100% leverage and to be used with caution and carefully).In the case of 2-4 unit FHA is still 3.5% down payment @Matthew Kwan @Carlos ValenciaThere are rules regarding FHA such as:- primary residence - you must occupy one of the 2-4 unit property as your primary over 50% of the year and the underwriter needs to believe you will remain and have the ability to live in there, any deviation from this and you'll get a whole laundry list of conditions asking you to prove why you should be believed to be living or will live there (if this arises dont be surprised, it just means the UW doesnt believe you).- SS rule - self sufficiency rule - gross rents of all potential units 2-4  X gross rents at 75% needs to meet 1:1 or 100% of the monthly PITIA payment or greater.

The individual proves their identity before receiving a code.I still do in-person showings as much as possible, but unattended showings are great for after-hours, weekends, or holidays.

Quote from @Sarah Rhee: I have a real simple rule for investing: never sell an investment unless you can move the money to a better-performing asset, or if the sale will move you closer to your goal.Your situation doesn't meet my rules.
