1) I used the real us median sale price of a house sold from the fed st louis for q1 2025 ( the number was later revised ) and then I deflated it to get nominal price using the bis residential property price data base ( bis was used due to potential other countries beig examined and i wanted a consistent methodology)

2) For each quarter I simulated the cost of a mortgage on a monthly basis and adjusted based on cpi without shelter to get real prices in terms of all other goods, for each quarter they were summed up in terms of real dollars including the dp

3) For salaries I adjusted the meidum nominal personal income of the us using the same cpi ( data for 2024 wasent out yet and used average growth rate for years after 2024)

4) To get all values in terms of income I either divdide total real cost of the loan, by real medium income of the year the mortagae was taken or the average of the real medium income over the 30Y loan
