We call RE operators "investors" fancier title, sounds better, implies more wealth, it's guru originated, the IRS will call you an operator and that carries just as much clout with me as "investor".

@Andrew Liu Does your operating expense taxes/insurance?

While operating as your own GC this will save you money, coordinating can be a bit challenging.Once you have decided the level of involvement you want in the project, just get bids from multiple vendors based on the same statement of work and compare the offers. 

Double closings are no longer allowed in the state of NJ so I've been told by one or two title companies that operate and do a lot of transactions in Northern New Jersey.

To avoid these, create an operating agreement outlining roles, responsibilities, financial contributions, and handling disagreements.

I moved out of it and now operate it as a rental (one unit LTR, the other MTR).

DFW AirBnB is getting expensive to operate and find good deals due to all the HOA regulations that are being implemented..If the property won't cash flow in LTR, then your option is limited to listing it, but I don't exactly know without looking at the numbers, as you can figure out some month to month strategy to lease the unit for a while.One thing that I always tell my clients is that when you are doing AirBnB or any STR/MTR, you are entering into the hospitality industry.

You can create a separate virtual account for each unit that will link to your main operating account.

Critical features for me: calendar mgt, manage client communication, communicating with team (i.e. cleaners), supply/operations checklist per property, and vacancy reporting. 

From my experience, many investors prefer to stay hands-off and avoid the day-to-day operations—managing contractors, solving unexpected issues, or finding a replacement electrician.
