I have never purchased anything 'perfect' but all of my rentals could have been rented as they were upon purchasing them. 

We’re fortunate to have an above-average income and live well below our means.This summer, we’ll be moving to Detroit (PCSing in August), and we’ve saved about $120,000 to invest in addition to having funds set aside for the home we’ll purchase in Detroit.The reason I’m posting is that I’m struggling to decide how to best allocate the $120k.

Purchase price: $275,000 Cash invested: $275,000About this homeBeautiful 2 bedrooms 1 bathroom condo in the convenient location of Rowland Heights, close to bus stop, supermarket, schools, shopping centers etc. newer counter top in kitchen and bathroom. 2 parking spaces and storage room.
