I have looked on Zillow but I'm not sure how accurate that is to use to gauge a pricing offer.

Most noteably your repair estimate and ARV needs to be accurate.

The bank is going to want more than 1-2 months of payment history to judge your credit worthiness, the longer the betterSo my advice is to A. start using credit karma immediately. it's free and accurate enough and B. if you want to use banks and debt to run your investment strategy, then you need to participate by their rules.

@Travis HouckYour mental block preventing you from believing you will raise funds is probably "the current Reality setting in".Raising  funds without understanding the deal, or knowing how to accurately run the numbers on a property (when you don't have a circle of friends and family with large amounts of cash) is probably a long shot.

How would you advise me to pull the most accurate comps?

Also I would like to get the official mortgage payoff directly from the lender to be able to better gauge where my offer number should be, how can I go about acquiring this legally and receive the most accurate number?

@Kevin Johnston the comments that @James Wise has provided are very accurate. 

They do not always show accurate data.

Does anyone have a MHP Lost for Pennsylvania with accurate contact information?

The 50% rule is accurate here if you are self-managing.
