My old pricing was $2100 for a year lease, and $2300 a month for a min of 3 months both will all utilities included.

You guys are going to blow up in this industry!

I paid some of the cost like utilities out of my monthly income. 

That 50% number includes things like maintenance/repairs, advertising, property management, water/sewer, utilities, vacancy, and yes, taxes and insurance. 

The two renters should cover your mortgage + utilities. 

I also do other bills at the same time, such as landscaper, utilities on my duplex, etc.  

You need a title report about $400, you need escrow costs $800 you need 3 month's of mortgage payments in the bank in case you don't find buyer right away so about $4500 for that, you need money for utilities, you need money to give the seller for their equity.

Does anyone have any guidance for a first time wholesaler getting their feet wet in the industry in general? 

Refinance to conventional, then find another property using FHA again, utilizing the 3.5% down instead of conventional 20%, and repeat.

It is that easy to gain more knowledge and be more skilled when it comes to the real estate industry.
