.$6,700 closing costs (which is factored into the loan) for a total of $145,400.Interest on the loan is %4.875Upfront costs are only $500 appraisal fee.$3,000 in escrow for taxes and home insurance.Monthly payment will be $1,375 which includes taxes and insurance figured in.The monthly rent is $1,650 so that will leave me a cash flow of $275.To remind everybody this is a SFH that I purchased 2 months ago and should be appraised at around $210,000.

When analyzing potential rental properties you need to factor in a vacancy rate of 10% and another 5% for repairs and maintenance. 

I got in around age 24, now 25, and I think that this is an ideal age perhaps maybe even a little older at 26.

I neglected to include in my original post that the offers were all cash, so I do not believe the closing schedule would be a factor here. 

Ideally, I would like to invest into flipping homes/renting out the properties in Florida.

Ideally I would like to use the profit to pay off some of my principal on current primary residence mortgage and use the rest for investing in a townhome that I can rent out...Thank you for your inputs!

The variable of life span is hard to factor in to know if it is worth it to you.  

Also, ideally, I'd like to hold on to my properties for 30 years until they are paid off. 

That is not the case with conventional loans (another factor to consider in your analysis).

You would typically want to have your contractor walk the property with you before you make your offer so you can factor the rehab estimate into your analysis and then you would have an inspection done immediately after you get the property under contract during your contingency period to make sure there's no other issues.
