As a secondary way to find good contractors, speak to contractor sales reps from any local lumber yards.

However when my agent contacted the owner for a viewing the owner says that he has two of the listed triplex for sale and that he wants to sell them together. 150k each and they are probably worth 175k each.So if this property works out it could be a great deal for me so my mind starts working on how i could buy them both.

Just trying to staying liquid for the upcoming clearance sale when the economy tanks.

But really it is little more risk than if I were to build a $600,000 single family home, especially because I live in a metropolitan area with lots of fouplexes (none for sale though unfortunately, because people hold on to them because they are money makers here).

Doesn't have pictures of the unfinished basement but you could finish the basement and have a small second unit: https://www.edinarealty.com/homes-for-sale/915-highview-loop-se-pine-city-mn-55063-5012713#/

Upon sale, you will have to pay tax on the 1250 gain (depreciation) regardless of whether deducted it or not.

I don't think I could be a real estate agent or broker, the sales end is just not to my liking. 

There's also a property in that area similar build and original just like the subject property, for sale at $170,000 and has been listed for over 140 daysI am wondering if you comp the property just like you would with a SFR, this home was built in the 70's and has no foundation built in 1970.

I am considering purchasing a property at this upcoming phila tax delinquent sale.

@Calvin Rankin if it was unpaid property taxes, it would be tied to the deed and that could block a sale.
