Definitely gave me a game plan on how to move next!

A lot of my wholesaler buddies are telling me it's common place to have to spend $50K+ on marketing to sustain the wholesale business right now. 

Planning the BRRRR it, should be able to rent it for $3,700 is my expectation.

I would ONLY consider that though if they had a real plan in place to catch up and I would likely verify what they said. 2.

This particularly holds true for Comtractors/ Sub Contractors who have notoriously bad business acumen.

My dad worked as a contractor for over 30 years and now I am looking to start a family business (he is retired).

You do not need to have a license to manage an apartment community.Property management can then be broken down into "annual" property management (normally a unit without furniture), a seasonal rental management (such as 2 weeks to several months up to 6 months) and then vacation rentals (sometimes for the weekend, a week, etc..).Each state has its different rules and licensing for each area of property management (annual, seasonal and vacation) as well as the different areas of management (association, apartment and property).I hope that helps.My understanding is that if you are an EMPLOYEE of the property owner you do not need to have a license; if you provide property management services as your management co owned business or as an independent contractor, then you do need a license.  

Zillow says it may go for $289k +/-My current tenants are using it for business and pay $2,250 a month.

PLUS expenses (maintenance = 10%, repairs = 10%, management = 12%), PLUS the business loan = around $393. 

Go to some REIA meetings, get some business cards and recommendations, and really put some time and effort into getting set up?
