Analysis of US residential mortgage market

Project Own
Overarching question
What are all the consumer financing options that exist in the market today for a home buyer? What are all the potential financial friction points that exist in buying a home?
Questions
What financing options are there? (e.g., conventional mortgages, govt. backed loan (FHA, FNMA, Freddie), jumbo mortgages, subprime, prime, Alt A held on balance sheet, etc.; reverse mortgages; fintechs that buy your new home for you while you sell your old one as a temporary source of finance; rent-to-own; what else?)
What are the characteristics of these financing options (e.g., LTV / downpayment requirement, cost, rate structures (Interest only, amortization), term, application process). i.e., what are the major segments by product type?
What is the size of each of these product segments? What is the historical evolution (and forecast) for these products?
Who are the major providers of these financing options (i.e., who are the top players within each product segment and the market overall)? What are origination channels (bank, mortgage broker, online, fintech)
How do residential finance providers typically segment customers (e.g., credit score, earnings (w9 or not), down payment amount, monthly payment, total housing budget, etc.)? What criteria are used?
What is the size of each customer segment in the residential finance market? What is the historical evolution (and forecast) for these segments?
To which segments are the various financing options available? (i.e., how do products and customer segments map together; which products are accessible to which consumer segments)
How do consumers decide how much ($) house to buy? What are the typical financial limitations (e.g., down payment size, monthly payment size, credit history, income variability, employment status)? What factors drive this decision?
