Likewise, in real estate there are Mentors by the dozen that all have “the secret to your success” available for purchase ranging from $289 to $50,000 (no joke on that upper number).  

My realtor is showing me duplexes ranging from 399-430k.

However, Cape Coral, Fort Myers, and Lehigh Acres all offer multifamily inventory in comparable price ranges of single family homes in the other markets you mentioned, which will allow significantly higher cash flow potential

i have a couple quick questions about using rental income to qualify.This is my first (possible) purchase and basically the home price is outside of my range to qualify on my own.

Houses that I've been looking at are $500 - $750K range.

Owner says rents are about $2-300 under what they could be but with the tenants being loyal and the way they are their own small community she recommends not raising rent.All 7 homes run off of 2 wells.Some differed maintenance but overall nice condition trailers range from 70s-80s model Owner says property manager/handy man lives next door and handles everything for her from maintenance to collecting and deposit rents.

Same price range, but mostly interested in appreciation. 

MLS will give you some, but you can look online to the City's website for the City owned real estate they have for sale, but those tend be up to highest bid.I wish there was a catch-all answer to this question, but there really isn't, because it depends on several factors - like what's your price range, what are you looking to do with the property?

Wethink it’s important as it allows us to check for Non-Sufficient Funds (NSF) issues and to determine if anapplicant is living paycheck-to-paycheck.

You’re spot on, you can potentially use a 3.5% down FHA loan for new financing if income and rents from the other three units are sufficient.
