Deals are out there, you just have to recognize them when the come on the market, or, alternatively, look to see which properties have languished on the market and make those sellers a low ball offer.  

However; are you saying that the broker will give you preferential treatment over his other clients, or that the broker has a lot of off market deals that he shows to his clients first before putting them on MLS? 

1, go to tax assessor's office to ask for some public record.2, find an agent to ask for help.3, use income evaluation which is an alternative when you cannot find comps to estimate a value.

Do you have alternative options to sell this deal if you do cancel?

I agree with @Jerry Kisasonak if the deal doesn't make sense then walk.If you are only worried about your reserves then look into alternative ways to pay for the deal, I have been purchasing small deals with hard money and then refinancing them after I have them rehabbed and have a tenant in place.Think outside the box.

Assuming you lived there for 2 years the tax treatment is more generous for your primary residence than it is for an investment property. 

I agree that laminate is a good alternative to hardwood and depending on what quality you get it can be more durable. 

Within one week we had a family move in (they were both doctors) and they've been perfect.The other side is going to get the same treatment as soon as he moves out.  

I am having some brick re-pointing quotes done for my town house in Virginia and a water repellent treatment was added to one of my quotes.  

If the property is not made available on these days, or acceptable alternatives, they will be in breach of the contract and more importantly, the inspection period will be extended by the amount of the dealay until such inspections are available.
