., talk to the broker to see if he's willing to work on a 30 day agreement, that way, you can both get to know each other.I know brokers who have their clients sign an Exclusive Buyer Agreement and if they don't get along, then the client can walk away with no consequences since it's better for both the broker and the buyer.I would think that in the commercial market, you really want to be represented by someone with experience, they can keep you from getting yourself in a bind.

I generally buy my materials similar to your second scenario, where I buy all the finish materials and the contractor provides all of the 'rough' materials such as plumbing pipe, fittings, wiring, lumber drywall, etc.I try to buy all of my materials in bulk orders...generally two bulk order per project...It depends on the schedule and the scope, but I will generally buy one bulk order upfront to get the project started & a second bulk order to get the project finished...Quantifying materials, and walking around Lowe's seems to take a couple hours for each order, but if you do a lot of rehabs you can create a list of typical SKU #s, which should help shorten the process.Also, if you buy in bulk you can generally send the order to the 'Pro Desk' and get 10% off the order.

If they have not paid there rent so i can just walk in and kick them out when there lease is up?  

Can someone walk me through the whole repair process, I mean, If the bank accepts my offer, when to start the repairs, how much time do I have to make repairs(assuming 30 calendar days for closing)?

The problem occured when we found out that buyers were just looking at our price on the MLS and walking past us rather that stopping in so we could educate them. 

The honest thing would be to move utilities immediately but the seller refused us a walk through (he just said I can walk out of the deal if I want but he has no time for a walkthrough) and I figure why - excessive humidity in the basement which he cleaned up quite well at the original showings.

Maybe just another opportunity to make money that allot of us would walk away from so there might be less competition in this area.

If will rent for less or association is more than walk away as well

I do take some issue to the owner backing out last minute after the time and effort I put into this deal, but I am willing to walk away.
