Hi, I am planning to move to Tampa and I would appreciate some advices whether should I rent or sell my primary residency before leaving? 

Are they abiding by the lease terms, maintaining the rental, paying rent on time, etc?

If someone rents the property so that they have office space to run some other business, that is not the same thing as renting the property so they can just re-rent it to someone else for more money. 

There is so much to cover you kinda need to drill down for us.First thing I would do is check VRBO and AirBNB and see what is renting in the immediate vicinity of where you are looking.

Revenue (rents) have not caught up to the value of homes OR, what I believe, value of homes have outpaced rents.

This assumes the market rent for the unit I will be moving into.My goals from entering real estate are 1. add diversification in my investments (right now heavily invested in stocks) and 2. house hack, so that tenants pay part of the mortgageIn my current market, I have two options: a. buy older houses, renovate, bring the rent to market --> this will cashflow, but needs a lot of time investment which I don't haveb. buy turnkey properties: --> renovated and already occupied by tenants but may not be cash flow positive.I found a property that's type B.

Live in for a year, then move and rent out the unit you were occupying. 

@Deepak C.you can use Turbo tenant to find tenants, going through a PM company is going to be your best bet for management - most will want 8-10% of the rents. 

For unpaid back lot rents, can a landlord place a lien on a TOH?

Anyway, we are thinking about renting the house that we live in right now for a year and moving into another house that we will house-hack, probably upgrade it with an intention of renting it in the future, and probably come back to the house that we live in right now.
