Quote from @James Thompson: Anyone had any experiences with working with flat fee agents?

This friend informed me of an investment opportunity in Dubai renting out flats (multi room apartments) by the room.

Normally, this fee is added when it is a flat fee service, or the owner is difficult to work with on pricing.Working with contractors is a difficult task filled with frustrations and missing timelines.

If it's not included in the rent, many companies charge a flat fee to monitor & pay utilities.2) Assuming you're referring to resident benefit packages, renters insurance, and other charges for services the PMC offers to tenants. 

Even the best managers charge a much lower rate, like a flat fee of $200 or maybe 25% of a month's rent.

Just some wire fees and maybe termination fees from the custodian and your time to consider...

Any suggestions on how you calculate the wholesale fees would be appreciated.

Are they flat fees or percentages? 

You can see if the title company/escrow company will pay them an invoice for a consulting fee.

Most likely because of their attractive flat fees!
