I don't think it is a good idea any more than you should also get your insurance broker's license, your title insurance license, your contractors license, roofer's license, and while you're at it HVAC certification, Electrical and Plumbing Master licenses.Some people do both, but I think for the majority of people there is enough to keep up with on either business that if you try to do both you do neither the justice it deserves.   

More details/example fees: Management Fee: 10% of gross rent collected, $50 minimum per unit.Leasing: One full month’s rent upon execution of a leaseOther: 10% will be added to each invoice for any repairs, maintenance, improvements, landscaping, and snowremoval for the Property 50% of late fees collected $50 lease Renewal Fee $50 per utility turn on $25 posting 3 day notice $100 per court appearance witness fee $50 tenant removal with bailiff or police $50 to meet inspectors for housing voucher programs, occupancy certifications, and/or POS or rentalinspections Broker may charge to offset Broker expenses for postage, key copies and other misc. expenses $100 set up fee $120 annual consortium fee ($60 March 1st, $60 Sept 1St)Given all this, how do I input it when I'm making calculations for a potential investment (do I put this in as >10% like 12%, 15% or 20%?

Hi Sammy,Make sure you know the flood zones and ask for an elevation certificate to see the elevation of the property, which will determine your flood insurance cost (if needed).

However, like @Ellis San Jose mentioned above, you will command more $$$ for your property if it is delivered vacant (unless you are getting top market rent for that unit).If you do sell with tenants, be prepared when the prospective buyer requests rent rolls, estoppel certificates, rent history, existing leases, rent due dates, security deposits, and any other written or verbal agreements.

This isn't like having to pay for a college degree or some certificate.  

There's also a ton of information on YouTube but be sure to vet the sources for quality, certifications, knowledge etc...

If they don't live there or are mean neighbors then you send it certified mail and submit the certification after 30 days if there is no reply. 

My biggest concern is the flood certificate says the main floor of the property is 3.7 feet above Base Flood Elevation.

Curious as to how I should sign in Part II "Certification" where it says "signature of U.S. person".  

Partly, this was due to the ease with which tenants can get certificates that legally bind many property owners to allow certain types of pets.
