REALTORS who help others buy and sell dozens of home every year have the local knowledge and professional experience to write a winning bid.
Now, all that is missing is a buyers who will listen to their REALTOR.
If you are serious, pick up the phone and call a Detroit REALTOR. Ask them how many HUD homes they were successful in purchasing. Then commit to that REALTOR. REALTORS have better things to do with their time than work with those who will not commit.
What you are asking is what REALTORS do to keep food on the table.
Best of success.
