I am an affected taxpayer as the property sold was located in Miami-Dade County and I a reside in Orange County and both counties are named, covered disaster areas. 

This has to do mainly with the timing of property tax payments for your own home (not for your investment properties) and your charitable donations.

The tenants in back apartment were married, was informed by the female that they were getting a divorce but she would be fine paying rent alone.

He isn't married, he doesn't have kids, he doesn't have family values.

Quote from @Andre Bertoncin: Hi, im 34, married w/ 2 young children.

Living in the property for two years likely allowed you to claim the capital gains exclusion... up to $250K for singles or $500K if married.

It's a good way to marry rehabbing distressed real estate equity capture with long term note income for retirement accounts for those that are interested.

When selling a primary residence you have lived in 2 of the previous 5 years you get a tax exception on profits of $250k for a single person and $500k for a married couple filing jointly.

This is due to bonus depreciation which allows taxpayers to deduct 100% of qualifying property costs in the first year, in addition to regular depreciation for new construction and improvement.

As a married couple, you can also take advantage of the $500k capital gain exemption.
