Send the resident tennat and their handler a rent increase notice according to your state regulations.

Is it a primary residence? 

The exact conditions required for a residence to be habitable vary by state, but often include an operable heating source during cold weather. 

I could sell one of my properties (condo) use, that money for flips in Atlanta within the next 1-2 years build up additional funds to acquire an apartment complex, and to grow my portfolio, but I want to hear from some experienced investors and what they would do if they were in a similar position.Current Picture/Portfolio: Property 1: Condo (Atlanta, GA 30328)Current Rent = $1550/MonthUtility Reimbursement = $200-300/MonthHOA $383 (In line with HOA's for other communities) Purchased June 05th, 2015 and resided in property until Jan 22nd, 2017 (Total of 1.64 Years)Lease Started Jan 23rd 2017 and Lease Ends on June 30th 2018.Current Equity 135,000 (Purchase Price)  - 85,000 = $50,000Current Comps Similar Properties are selling for $155,000 to $170,000Current Mortgage Terms: 15 yr Fixed 3.325% Monthly payment of $996 (Includes Insurance and Property Taxes)Anticipated Total Earnings if Sold at End of July $64,500 (Sell Price $155K) to $78,500 (Sell Price $170K)  Property 2:Town-home (Peachtree Corners, GA 30092)Current Rent = $2000-4000/Month (AirBnB) 60-70% Occupancy since November of 2017Purchased July 28th 2017 and currently residing in basement house-hacking with my younger brother.HOA $325/Month Covers, Water, Lawn Maintenance, Sewage, Security GateCurrent Equity 336,000 (Purchase Price) - 265,000 (Remaining Loan Balance) = $71,000Current Comps Similar Properties are selling for $345,000 to $360,000 due to private/public school ratings going up shortly after purchase.Current Mortgage Terms: 30 yr Fixed 4.326% Monthly payment of $1823 (Includes Insurance,PMI, and Property Taxes.)

Here's a sample of fine print:“Borrower shall occupy, establish, and use the Property as Borrower’s principal residence within 60 days after the execution of this Security Instrument and shall continue to occupy the Property as Borrower’s principal residence for at least one year after the date of occupancy, unless Lender otherwise agrees in writing, which consent shall not be unreasonably withheld, or unless extenuating circumstances exist which are beyond Borrower’s control.”Different lenders have different "fine print" statements that may be more grey and confusing.

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

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

One of the easiest ways to get into rentals is to add a rental unit to your primary residence or to purchase a home as a primary residence and then move out and turn it into a rental keeping your low-interest rate. 

If that house is still available I would get it under contract as soon as possible as a primary residence and then figure out the details in the coming weeks/months.
