My concern with the place is in the master br there is about a foot long mold spot on the ceiling and it feels like the floor in the second br is unlevel. 

Your construction costs are off by almost $50 a square foot unless you have some kind of deal already inked.

I do have the rental income of all the properties but the valuation he provided didnt provide me with any details with how he got the price per square foot that he used.Is there something i'm missing?

You probably should be under $3 a square foot installed on that. 

I am new to this so I am barely dipping my foot in the water but I hear so many great stories I feel like I have to give it a shot.

That's a pretty decent price/square foot for Casa Grande, as long as it doesn't need a whole lot of work.

We created a short list from our work and started flying out to these cities to meet other BP members and explore the market by foot.

If they , their dog, their child or a guest do damage then they foot the bill for the repairs.He stated he was working on the lot and as a result a window was damaged...he pays.Get the work done and bill him for the cost (do not take it from his deposit).

Can anyone share with me a good rule of thumb in terms of the price / sq foot we should expect to pay for insurance in this area?

When it comes to valuing the below-grade vs above grade square footage the appraiser gives the basement a lower price per square foot.
