A bathroom fan is probably going to produce very little, if any results at all, and it is never a good idea to vent anything into your attic -dry or otherwise. 

What hurts the return is how minimal the leverage was.Interest rates have risen substantially but are still low by historical standards.I suspect your best option is dictated by what sort of appreciation you expect going forward.  50% appreciation in the last 5 years is pretty good but, due to your level of leverage, it did not produce a substantial ROI. 

Many times I read that going direct with sellers produces some of the best deals, but what if it's listed with an agent and things seems to be taking longer than desired? 

A guy you pay $15.00/hr to knows almost nothing through they may appear to by the way they hussle and swing a hammer but trust me a trained laborer will produce good quality work and a lot more for you.

Keeping the current financing in place but selling the unit with some sort of owner financing lets me (I think) enjoy the benefit of a cash out refi at a great rate while reducing/eliminating my exposure to the taxes and condo fee on the current property, freeing me to deploy that capital against a more CF producing property.

I moved to Detroit 3 years ago with big dreams, a pocket full of cash, and was naive about what I could expect and produce here in Detroit on my first project.      

Mainly because of the potential CapEx cost compared to the minimum income they produce. 

I've included a $6,000 cost for fire restoration as a miscellaneous item but it does not show up on this report.I've used a Deal Analyzer from FortuneBuilders and have become dissatisfied with it, but I'm feeling MUCH MORE CONFIDENT with the use and presentation format these calculators produce, so thank you to BiggerPockets for creating these tools and the website to help investors, especially for a rookie like myself.I believe she's negotiable as far as a price is concerned and I was thinking of beginning to start negotiating at $269K.

If I can produce seller's schedule E's or a signed operating statement with detailed operating expenses below 20% they will use actuals, but with hesitation. 

You do not want to get tangled up in a discrimination suit because you turned down George who brought a dog into the unit and produced a certificate from some online sight that says the Saint Bernard he has in the apartment makes him feels secure during rainstorms and full moons and this keeps him from having nervous seizures.
