 `How to calculate monthly mortgage payment affordability?`
 ```I assume you are looking to calculate how much house you can afford (both in per-month mortgage payments and in the total value of a home) based on a number of factors. Luckily in this age of computers, there are a number of calculators out there that make it easy to calculate a mortgage payment affordability based on how much you make, your debts, the length of the loan, and the loan's term-length. I've listed several below: Mortgage 101's calculator "How much can I afford?" - has detailed options to play with [http://nt.mortgage101.com/partner-scripts/1070.asp?p=mtg101&pw=760] Lycos "Affordability Calculator" - simpler than Mortgage 101's [http://mortgages.lycos.com/Mortgage_and_Finance/Calculators/AffordabilityCalc/] Basically, what lenders (and these calculators) do to calculate your affordability (e.g. how much you can spend monthly and how much house you can afford) is calculate your "debt-service ratio". To do this, add up all of your monthly debts (including credit card debts, car payments, student loans, etc.) The sum of your monthly debts plus your monthly mortgage payment plus any mortgage taxes, fees, etc. should add up to *no more* than 40% of your monthly gross (pre-tax) income. Additionally, the mortgage and its associated taxes and fees by itself should add up to no more than 30% of your monthly gross income. [more info: http://www.fyilondon.com/londonroyallepage/mortgageinfo.shtml] Of course, this is just a rule of thumb so that you don't end up with too little each month to afford food, clothes, random niceities, and the unfortunate occasional unexpected repair expenses, etc. I hope this works out for you, and please let me know if I can be of further assistance. Take care. --Joey```
