Haroon,It all depends on how much you value your positon being that you are using your "good credit" and your ability to show income to qualify. 

I have had a different route and went from SFRs to MHPs since those are a better fit more my knowledge, skills, and abilities. 

So from a strategy of maximizing your ability to leverage, this allows you to keep as much money as possible free to buy more investment properties. 

However, I am less confident in my ability to find it.

Also I have the ability to use a VA loan for my primary so I would not need to put any money down on new primary. 

As far as updated, I’m confident in my own ability to do minor upgrades and I have contacts for electrical work if needed.

In Columbus OH the house committee actually recently passed a bill that blocks towns and counties from passing ordinances to prohibit businesses or people from renting property for less than 30 days.

@Frank Yaccarino To add more to the conversation you need good or even great negotiating skills, the ability to estimate repairs (or know a contractor who can), a way to get accurate comparables, time, and dedication. 

Development is a complicated business, the more knowledge you can acquire with more velocity improves your ability to increase your income.Personally, my best days were when I would be tasked with managing a project (or part of it) and could at the end of the day ask a TON of questions about how to do it, what happened, what went wrong, what could be done better, and what could be done better than anyone else.

It takes a lot of hard work and mistakes but income potential is only limited by your ability to learn new skills and put in the work.
