@Manolo D. is right that you are taking a big gamble.  

This is where accurate, consistent, and timely documentation of maintenance and management activities (as related each tenant) can save your bacon because the documentation will provide the proof regardless of who bears the burden.

Im a wholesaler and just wondering how accurate are the results on them?

But I can take over your payments and pay them religiously for 2 to 3 yearsOption two we turn this into an investment property find a buyer that just missed financing and have them rent for a while, work on their credit, pay down some debt, and then when they buy it, they pay full price, you have a sale  without a real estate agents commission, without closing costsIt takes 2 to 3 years to get that done and you do have to have an insurance policy and pay taxes but you got some great tax write off's from the IRSSo Mr. seller which one of those you like the best, listing it with an agent and paying the costs to sell, maybe paying 5 to 10 grand out of your pocket to get rid of the housedealing with a property manager and gambling with landlord-tenant law, me taking over your payments, or turning it into an investment property and selling it down the road for full price, no commissions, and no closing costs?

My actual construction days were pretty accurate but I didn't include any personal days. 

I can assure you that any returns that I quote are accurate my friend.  

Is it possible to get a accurate estimate on a property repair value and rehab cost without using the MLS? 

My problem is understanding how to accurately underwrite these deals.

I pulled some comps from *******************.com (don't rally know how accurate it is) and saw as low as 35k and high as 110k.

@Gamble LiAround here (Fredericton), the inventory on 6-10 unit buildings is pretty tight  - though there are a couple for sale at the moment in a part of the City that is a little less desirable.
