You should be holding personal interviews and gathering all pertinent data.

Everything on the sales sheet was accurate and we agreed to allow the Buyer out of the sale, because there is no point being in a sale with someone that does not want to buy.

To be more accurate, the "average" being 3yr lease, WITH a automatic annual rent increase (because we are pro's at this and actually know what were doing", it's more accurate to say $90,792.00 gross revenues for..... $300.00....... 

I saw such info online and I was not sure whether it I was accurate.

I’ve never used any form of skip tracing before so can you please tell me how accurate and useful it is?

Agent asks me when do I want to walk the property.question: do I search for and hire a contractor to walk the property with us so I have an accurate estimate of cost or should I wait for the due diligence phase of the deal?

That will give you the most accurate info you can get. 

One thing I've used to draw some boundaries for a business plan, is gathering as much as I can from "Biggest mistakes" or "Most Common Mistakes" lists posted here and elsewhere.

Hey @Rolando DeLeon - I recommend staying away from the data aggregator sites like Rentometer because although they're helpful, most of the time they pull averages from specific regions and that might skew your accurate market rent.
