You picked a great community to join.. have you checked out local comps to gauge the market vibe yet?

From there we identify properties that could have some potential and if you are interesting in diving deeper, 1) we do a thorough video walkthrough to give you a realistic look of the property, 2) we give a ballpark estimate of rehab costs (we do 40 a year with our GCs o we will get pretty close), 3) we talk through market rent with our property management team, ARV, and potential highest and best use.Ideally you find great investor agents who know their market really well and have a network of resources to provide you with enough confidence to take reasonable action. 

I have been investing in the stock market for 5 years and I am now transitioning over to real estate after doing my research on real estate for the past two years. 

BTW: most owners that have hired a PMC, don't want to speak with you, much less meet with you in person to hear a hyped-up sales pitch.Also, you want to do rental arbitrage - so, you will need to be properly licensed to manage properties you do not own as required by your state & local laws.- why would an owner want to do business with someone NOT properly licensed?

I, too, am in Tampa and I've been a lender/banker and a Real Estate investor in the market since 1996.

  (2) Variable cost: platform fees from Airbnb and VRBO, lodging/hotel/transit or whatever pass-through tax your local AHJ requires, cleaning fee, cost of replacement for consumables, repair and maintenance, etc. 

I avoid the multi-family market here, so unfortunately, I will not be a good go-to here, but I am confident you will find quality resources and help here on BP.  

I would also check out NARPM for a list of local property managers. https://www.narpm.org/about/why-use-a-narpm-memberBest of luck!

Focus on learning market trends, property valuation, and different investment strategies.

I would recommend attending some local meet up groups or REIA meetings.
