Aside from all the great reasons he mentions above, as Melissa also states in her post...Central Florida is the only true year round market in Florida.

While it's true it takes a lot of capital to buy investment properties for 20-25% down, there are many other ways to get going.

By amazing I mean very communicative, easy to work with, met deadlines, and stayed true to their loan terms. 

None of that is true, at all (I could go over why Realtors believe that, it involves both self-selection bias and confirmation bias acting together, but that's not strictly relevant to your question), but that listing agent believes it's true, and will advise their seller client to throw your FHA offer in the trash, if they have any other options at all in terms of which offer to accept, which is very probable in this market... because, guess what, all your competing buyers also have Realtors, and they too are advising their clients to use conventional rather than FHA.

Unfortunately most banks and lenders are not willing to pay a true professional that understand investments, or even how to read a tax return.

Ha, true!

This is especially true if you plan to invest in real estate in the future.

I don't think anyone would advise someone to buy an investment property without first learning about the process, I think the same should be true on what to do once that leap has been taken.Open to any suggestions or advice.Thank you

Not true.

U.S: It will remain true that the frequency and substantiality of sales will be the most important factor.
