I had recently bought and refinanced a car when the brakes went out on my college ride, rate shopped on the house over a long escrow period so they didn't get viewed as rate shopping, and I financed the renovations through 0% credit cards, so in total had 8 inquiries and multiple new accounts in the last two years. 

Buy the car, detail it, throw some new tires and brakes on it, change the oil, wiper blades, and try to get $9k.

I liked this property because much of the CapEx was done, but I'm pumping the brakes if the roof isn't going to last longer than 10 years.The property would cash flow about $300-$400/mo net with initial projections as a long-term rental, but I'm not sure what the insurance cost would be now. 

If it's not publicly listed the bank is not putting the brakes on a foreclosure.

You have a tiger by the tail because of price and terms you paid, I agree with those that have said to put on the brakes.

@Jerry Padilla that is a great point about limiting my pool of buyers, and lease braking, I hadn't thought of that.

I don't go to my doctor to find out if my car needs new brakes.

I'm from Seattle area and looking to buy a duplex investment property but 99% of such properties in Seattle area are overpriced, rents below market, barely braking even, and still getting too many offers within a couple days.

Now it has 180k miles , I’ve put in new brakes and muffler over the years . 

Since you're buying pre-owned at least make sure the brakes and tires are new and they give you a warranty.
