I bought a house from my father, essentially (it was part of his inheritance) and we paid a realtor a small fee to do all the paperwork, assist with the title search, and file the lien (it was financed by my father, but with official loan terms and we both wanted the safety and formality of a lien). It was a decade ago so I don't remember how much, but it was *way* less than we (or him, really, as the seller) would have had to pay an agent. He passed that saving son to me, and you should request that your LL do the same. If 6% is a standard commission in your area, then ask your LL to knock 5% off the cost, minus the fees for the paperwork, etc. Then you both come out ahead, though you slightly more than him (assuming the fees are less than 1%, which would likely be the case unless you live in a very cheap housing market).
