Contract language would be interesting...
I've sold with and without and also 50/50 where a broker brought me the buyer...
I've seen both brokered transaction and for sale by owner blow up...
The ones brokered had the job cleaning it up including legal fees and settlements...
For Sale by Owner can be a lonely place especially in a highly regulated market where tons of disclosures, etc are required. There are some sophisticated buyers just waiting for For Sale by Owner.
A good local expert Realtor just makes it look easy which is a good thing... so many pitfalls these days...
I'm not that old but can remember when my rental agreement was a single page plus inventory and condition sheet...
Now it is 28 pages most of which are mandatory disclosures covering everything from city smoking law to rent control, Meagan's Law, Lead and Asbestos... etc.
