Compared to hotter parts of DC the units she features are very affordable, but they tend to be condos, which the OP wanted to avoid.

I don't have any real insight on the value of the OP's teaching class question, but $15k is a lot of money and can pay for a lot of mistakes. 

@Justin Fox If you refi'd sooner than 6 months based on ARV than you used a commercial/portfolio loan and not a conventional Fannie/Freddie loan so it really just depends which type of financing the OP is looking for.

Hi, I have just come across an opportunity to invest in a "Co-op" I am not familiar with investing at all, so this is where I need help to find out if this is a great deal, good deal, or not a deal at all.

I think the key is either having a manager/partner, or being prepared to self manage, and expect it to feel like a part time job.Per your OP asking about comparable properties, airbnb is also a great way to get a feel for a neighborhood.

As with most threads, we need to take the OP largely at his/her word, and make comments accordingly.

If you are going to be in business, any kind of business, including the RE business, you should understand business, take business classes, go to the SBA, go business tax seminars, business clubs in your community will have business leaders and others that can advise in many areas that will only broaden your abilities to operate in your business.As to the OP, I don't really buy the loophole definition or the stab at it, thing is there really aren't repetitious operations or tricks used long term to build wealth or advance yourself.

The ROIs that the OP quoted have to be the 30 year ROIs. 

Since then they have invited me to several active flips that are in the construction phase to explain different aspects of flipping, they gave lots of information on a co-op that a group of them got together on.I have been seeing things as if what they said was true.

The op is having problems with nuisance complaints.
