Your realtor shouldn't do your reno
The brothers have two businesses: acting as real estate agents and doing renovations. That creates a conflict of interest, because they'll have an incentive to feed their home buyers into their reno business. If you're looking for a house, they're going to want to guide you toward properties that need major renovation, so that they can cross-sell their reno services to you.
The buyers should separate their house hunting from the reno process (if any). If they decide on their own to buy a fixer-upper, then they should shop around for someone to the reno.
