Doc:
Does Doc come away with two horse from the battle?
Oh and how much does a small little house cost?
No -- the horses were caught outside the portcullis and you had to abandon them there to avoid getting killed by the onrushing hordes of Blues.
I will generally refer to the Pathfinder price list for cost estimates (you cannot assume that this is the actual cost, but it will give a sense of value based on your income and treasure found, etc.) The link is here:

It does not mention houses per se, but it puts the price of a carriage at 100 GP. Say that's roughly equivalent to a mid-sized nice car in our world -- say $20,000 off the lot. Houses around me range from $100,000 for fixer-uppers to $500,000 for pretty nice -- so a hovel/garret would cost about 500 GP while a small townhouse in a middle-class section of town would cost about 2500 GP
