Also, you may want to speak with a real estate tax specialist about this, but remember that if you change a primary residence into a rental, then you can count the net income as an addition to your salary and the loan is not counted against your credit.I looked at your spreadsheet and noticed that you may be able to cut costs by looking into different insurance companies with lower rates, but equal coverage, and also by appealing your property taxes.  

I find an appeal to live downtown during my retired years, but only if it's one of a couple options.From a macro standpoint, our population is still growing (and will likely continue to).  

The returns are very appealing, but the design review is legitimate.

I would agree with @Ben Leybovich that the larger complex is much more appealing as the overhead can be accommodated without as much of a detraction from margins.

I let the marketing attorneys appeal taxes for free (I pay half of 1st year savings if successful), but they are only at about 10-20% success rate recently, and have not won any of the second level appeals.

Additionally, buyers are rarely willing to pay you back $200k to increase community appeal.

Personally the higher taxes and insurance makes them less appealing. 

I'm on the other side, the idea of going back into debt after having F&C income properties is not appealing.

I learned to make sure all my leases ended between may - sept to avoid non-optimal turnovers, paid for professional photography to attract higher demand, and invested in stainless kitchen appliances to increase appeal to get a higher rent.In the last 3 years, rents have done some serious climbing.

We tend to appeal to the lower officers who are married and therefore want a house.
