@Mostafa Koperly..I would agree at face value with @Robin Simon and your alluding to contact banks/CU's, but I can tell you credit markets for construction are tight. 

But you need to learn all about landlord/tenant laws, how to do basic repairs, know what average labor and material costs are for common projects. learn about payment systems, how to interview property managers, tenants and handyman services, build a team of realtors, contractors, title, hard/private money lenders, inspectors, appraisers and soooo much more. 

If anyone has any advice on starting construction, good place to find cheaper trim, doors, cabinets LVP etc, or even people in the Minneapolis/north metro that you would recommend for the job I would love to hear it.

-New construction costs of $200/sf @ 1,500 SF total, (750 per door) = $300k. 

Most who operate property management companies profit off of ancillary businesses that are interconnected such as brokerage services, construction etc. rather than the actual property management. 

The home was a big interior and exterior clean up with minor construction.

Charlotte is a great market (though it is seeing a lot of new construction this year!). 

If possible, find a local attorney who specializes in real estate or construction disputes to represent you at the hearing, given you're out of state.

IF you have a recorded mortgage and it was a normal sale handled by a title company and the buyer wanted title insurance then you would have had to be paid off and signed a mortgage release or a reconveyance deed.One way or the other if you want some constructive help you need to clarify what you actually did..

Investing in new construction can make sense here given the strong appreciation and you end up leveraging basically the same amount of cash and have an asset that's not 60+ years old or more.
