I had the inspection and estimate done this weekend, and it is about $15,000 higher than I originally ball-parked on my walk-though estimate.My question is: if I offer to remove the Contingency only if the Seller agrees to a sale price of $155,000, how likely are they to accept it? 

It's reviews some of the due diligence process I went through while I was living in Seoul to identify where I wanted to invest and how I inspected the neighborhood.Take a look and if you have more questions, let me know.

I called the Bureau of Housing Inspection to see when the Green Card was due, and they said that the house has never been registered; I have a couple questions.Is a Green Card Required for a Quadplex?

I would also put an inspection contingency on every offer you submit so you could still back out of a deal if you're not satisfied due to inspection.

Make sure you do a complete inspection and or have it inspected.It will keep you occuppied and hopefully out of trouble,  You will learn alot.Run the numbers yourselves and on BP.  

Identifiers, price, contingencies with dates (cash/loan/closing cost, appraisal, inspection/ title co).  

Biggest issues I see with the home from a home inspection standpoint would be the lack of insulation in the crawlspace and the dryer vent blows out into the crawlspace.3.

Assuming you have inspected the property to the degree you know what you are buying within reason, you understand the sale terms and fees, and so on then they are fine.

Also it has two unused oversized garages in the complex that I was thinking might rent for 75-150/month.It looks like inspection issues are a hang up anyway.

Real, substantial success versus using say a 10 day inspection period.
