It was in rougher shape than I anticipated. 

Everything has an anticipated life span but not everyone is going to own the property throughout that entire life span.Roof example, you buy a house with 5-10 yr old roof, you realistically want to hold on to it 10-15 yrs max and then 1031 into something bigger...

I also spent about 3x more than what I anticipated, and I did most of the work myself. 

The percentage will depend on the condition of the home and when you anticipate the next big ticket item will come up.

My rent will likely be higher than anticipated.

There was just one BIG problem that I hadn’t anticipated…One of my banks, at which my personal unsecured credit line is 40k, suddenly was no longer offering the 0% interest balance transfer promotion!

It's just that I'm anticipating a "better" tax situation next year - that is, for personal medical reasons in my family, I'm anticipating a lower level of income next year.

It also largely depends how far out of Boston you anticipate going.

Rent I anticipate to get with carpet vs wood floor 

House could have rented for 1200 to 1400, my hoa fees and mortgage were about 945, so it did not make sense to rent and we knew we needed to list it.We anticipated being able to make 5 to 10 grand on the house.
