I'm reading up on books and articles on how to do this but sometimes it's easier to join social groups or talk to people close to me that have done it before.Right now my goal is to get pre-approved for a loan and to learn from others.

The super came and said it is because of the wrong paint used not the vent. 

My problem is that every six months I have to move (summer season North Carolina, winter season Florida) so I can't use first home trick.

I'm closing on a house that used to be a single family, but was converted to be a duplex.

With no rent for this current month.

This is a very common agreement, in your space your problem and they also should have insurance that if its extensive insurance would cover it. 

No one can explain how this happened and it was recently surveyed 3 weeks ago with the measurements in the attached picture.

I am so frustrated and saddened this person did such a thing but was told that If I sell the property, which I prefer to do by seller finance, the code enforcement cancels.

(Roth's being an exception.)CPA Tom Wheelwright has a chapter on this in his book Tax Free Wealth and agrees with what I just noted. 

What steps are you taking now to make this goal happen in the next 6 months??
