I was quoted the following:Single family home/Fee Simple townhouse- 20% down payment: 5.875%- 25% down payment: 5.625%Condominium-20% and 25%: 6.375%- 30% down payment: 5.375% 

Do you pay a monthly fee? 

I imagine the fees could eat you alive with multiple accounts, but being I am totally new at this, I'm not sure what is the best method.Thank you for your time, knowledge and advice in advance.  

Our realtor said she can put together the FSBO paperwork, but are there different fees (or cheaper?)

I generally think the fee is worth it if I don't have to constantly worry about the property, and don't mind the hit to my cash flow since this investment is absolutely driven by appreciation. 

Not sure if I want to hang my license with a flat fee company to have access to the MLS and maximize return in investements.  

Are the Realtor fees relatively similar to a normal real estate deal?

Your agent may willingly bow out or may agree to some small flat fee to represent you.

And you are right, I did not account for a management fee since I am planning on managing the property myself.

If the building is brick bring a good mason who can point out possible pointing issues, pushing walls, failed lintels, etc.If you have a flat roof or even a normal roof have a good roofer check it out.
