New to 1031 Exchange

[Felipe Ocampo]

I am currently selling a rental property(just signed the offer) that I have had for about 6 years and just realized that the capital gains will probably be pretty steep so I may want to do a 1031 exchange. I originally bought the property for about $208,000, will sell it for about $235,000, and the depreciation has been about $7563 each year. I put about $6000 into capital improvements. I know I need to include closing costs, which I am assuming were around $7,000 for each transaction. That is almost $8,000 in capital gains assuming a 15% tax rate. I currently own about $147,000 on the mortgage. 

My questions are: 

1.How complicated is the 1031 exchange process and is it worth it in my case?

2. Do my numbers above look correct or am I missing something?

3. How quickly do I need to identify the replacement property/properties?

4. What are the typical costs to do a 1031 exchange?

5. Any other suggestions or recommendations?
