fusangite said:I too have had some difficulty dealing with real estate prices in D&D. Any general information about land prices in the high fantasy universe would be great.
Well, a good rule of thumb is that farmland or grazing land sells for 25 to 30 years' rent, and that residential real estate (subject to depreciation of the building stock, fire insurance, etc.) sells for one thousand weeks' rent.
The rent of farmland is equal to its production minus subsistence living for enough farming families to work it. The rent of housing is typically 25-35% of the income of the types of people who would live in it.
That is all in an orderly condition in which tenure of land is secure, warfare and dispossession relatively uncommon. If there is a significant rate of risk in real estate ownership, land prices will be lower. If society is unusually short of capital (and therefore unusually rich in rival investment opportunities), that too will reduce the price of land.
As a general rule, the price of a piece of land is roughly equal to
p = R / (i + r + b.d)
where R is the annual rent, i is the opportunity cost of capital (ie. the interest rate), r is the annual rate of risk, b is the proportion of the rent that is effectively paid for improvements rather than land and d is the annual rate of depreciation of the improvement stock.
You won't go far wrong using i = 0.03 (for a rich society) to 0.07 (for a capital-starved one), r = the number of invasions or civil wars in an average century, d = 0.03, and b = 0 for farmland and 0.7 for urban real estate with buildings in reasonable condition).
I know nothing about Waterdeep, but assuming that it is like enough to mediaeval London, figure that a typical labouring family has two working parents (each earning 1 sp per day) and two children on half wages, plus non-earning dependants. They will earn 21 sp per week, so a two-room apartment without bathroom or kitchen will bring in 5-7 sp per week. Guess that a typical tenement is three storeys with four such apartments on each of the upper storeys, and shops on the ground floor earning double rent. 80-112 sp per week. In reasonably good repair the place might sell for 8,000-11,200 gp.
