I have gotten commissions for putting a tenant and landlord together, but this was always agreed upon with the owner before I brought the tenant. I always ask for half of the first month's rent (paid to my broker), but I have settled for less. I have also done this for free many,many times. Renters may buy from me one day and homeowners may sell with me one day. I call this free advertising!... more
The owner, as others have pointed out usually pays the commission. Think of it as a finder's fee.
As for credit score, you can use many resources, but sometimes pairing up with a good loan officer can accomplish the same thing for free. This is especially effective on Lease Purchases.
Good Luck!... more
