How to analyze Apartment Building

[Jairmiya St. Hilaire]

Hi Eveybody! 

If you had a colleague of yours inform you about an apartment building for sale, how would you analyze the deal? What would you ask of the owner to help you analyze the property to ensure it is a good investment? The only thing I would think to ask the owner is for the T12, pro forma, and rent roll. I also would probably ask the owner why he is selling the property so that I could create a win-win situation for us both, possibly seller financing if he has a good amount of equity in the building. Let me know what else it is I should be asking or looking for? Respectfully, Jairmiya
