Or is the tax implications of higher valuations cancel the positive effect?

You must individually own a set percent of the new purchase equal or greater than your selling property in the same tax paying name as when you sold.

Currently, we are leasing the property, generating a net profit of $380 per month and living in Missouri.We are contemplating the decision to sell this property and potentially gain $239-278K payment to buy additional investment properties in Missouri given the rising rental rates in the area, we anticipate increasing our rent and potentially securing a net monthly profit of $780 (annual$9,360).While we acknowledge a monthly profit, our concern stems from the apprehension that the property might not fetch as high a price in the next five years or that our HOA fees and taxes could escalate.Given this situation, what course of action would you recommend?

Can anyone tell me what licenses I need and what taxes I'll need to pay?

Simply reducing the assessment and corresponding taxes reduces expenses and immediately increases the value.

I'm a new Tax liens, deeds investor in the DC, MD, VA areas. 

Last two years of tax returns, credit check, pay stub, etc.

I have done 35 mill worth of deals , own a PM co, have 12 admins, 25 or so contractors, have purchased props from tax lien sales, sheriff auctions, short sales and more, nothing I have not done .

I am still trying to learn the bookkeeping/accounting side of it so that my CPA won't scream at me come tax time!

If you truly must and are looking for where to get digital staging done you can find it on sites like fiver for a freelancer, however if you rent to someone and it is digitally staged and it does not look like the pics they will trash your review and possibly get a refund.
