I own property MD should i use a CPA from MD or the state where i currently reside?

Here's the scoop:The house has been a rental for @ 6 years with decent income; clearing @ $6k + annually; no mortgage; current market value @ $160kI have probably broken even at this point with initial cost and all (many many) upgrades;  have no idea what the tax situation will be if I sell; would not be able to use 2 year personal residence - no cap gains rule.  

We are open to occupying one unit of a duplex (to secure a lower interest rate) for example, and have a good friend who would rent a room in our residence - with an extra apartment (or possibly 2 if there is a basement) creating multiple revenue streams to quickly repay a relatively small mortgage.

I own 2 condos in the same building (~$150K value each) in Logan Square, one is financed through a local bank that sold the property as a foreclosure several years ago and the other we paid for through a HELOC on our primary residence. 

I'm a newbie to BP and currently reside in Beaufort County SC.

I have my personal residence and vehicles on the same insurance, and my personal residence (worth much more) is less for insurance.  400-600 is the range i was shooting for. 

Last summer I purchased two seller financed properties in addition to the 3 properties I own with conventional financing.I currently do not own a primary residence.

I am being 100% honest in what I am about to type: I bought my grandpa's house two years ago, and lived in it as my primary residence for 2.5 years.

I currently reside near Canton, Ohio.

After talking with an attorney on if repair was responsibility of lower residence or my residence, knowing it was builder's fault but would be difficult/useless to try to get them to fix it 15 years later, we fixed the retaining wall for $9K.
