(I realize there are alternate structures - this is how we are doing it.).

You want an accountant who can help you strategize and who is responsive when you want to know the consequences of the financial decisions you are making throughout the year.There are over 20 real estate accountants on this site.

They have daily webinars, you can call your mentor pretty much 24/7, so it's real interaction.

Yes you can but it depends on the lender some lenders do not allow due to overlays and in house restrictions.

I’m looking for local forums, groups and or networking opportunities in Washington D.C where I can connect with other investors or wholesaler professionals.

Tons of seasoned members here to also help offer good advice as well as keep new investors from making mistakes.  

Pleased to accept the recommendations of those more experienced than I and I thank you for your advice!

Do you meetup with any local groups?

If that is the case then you may just need to be realistic about what it is worth - cash buyers are usually investors and there has to be enough upside for them to make money.Have you talked to your realtor about the feedback received from people that have seen the house?
