<prompt> Human: Hello everyone!Ive been working on putting the numbers together to purchase a house in Southern California with my fiancee. My current situation: 53,000 income 56,700 in liquid investmentsavings accountchecking account 30,000 in a ROTH IRA, company matches what Im contributing, etc. Living rent free with my parents Zero debt Credit score is 813 Fiancee making 40,000, also living rent free at the moment She has 10,000 in savings She has zero debt Her credit score is 780 No car paymentsSide note about the wedding: Her parents are giving us 10K to pay for it, the honeymoon, and add to the house down payment. The company I work for pays for my gas, phone, health, dental. I kind of dont have any bills right now. She pays 300 in bills a month.Together after taxes and retirement stuff, we make 5,500 a month. My father said hed give us a loan for 100,000 at 3, bumping up our down paymentpurchasing costs to 150,000. Were open to having friends live with us to offset mortgage costs I have a friend who loves home improvement projects.Were not going anywhere anytime soon our families are in this area, shes getting her masters for free through work, I love my job.I read the guide for purchasing a house, used the calculator and it says buying is cheaper. I read thru all the extraneous costs that come with buying a house.All the stuff that I read here said you want your mortgage to be 20 of your monthly income. Its looking like we could get it to be around 30.For the houses that we want, the price is from 450,000 to 500,000.I guess I have a lot of questions: 1. What do you all think about this idea?2. Can we afford this?3. What am I forgettingnot doing?4. Is there a step-by-step list for house purchasing?5. Anything else?I feel like I am kind of blinded by my ambition to own a home. Ive been saving for a while for this. My older brother bought a house recently, and hes fine. Im following what he did.Thank you for your insight and help. Im a pretty sporadic thinker, so if it doesnt flow very well, Im sorry.  <response>: My father said hed give us a loan for 100,000 at 3, bumping up our down paymentpurchasing costs to 150,000.When you get a mortgage, you will have to sign documents stating that your down payment is not borrowed from anywhere. Lying on a mortgage application is a federal crime. The reasoning behind this is lenders want to make sure you have skin in the game I.E. your own money. If you borrow the down payment then you are more likely to simply walk away if the value drops.Also, 500k is alot to spend on a house with a combined income of 100k. I think you need to work on getting your combined incomes higher before buying an expensive house like that. All the stuff that I read here said you want your mortgage to be 20 of your monthly income. Its looking like we could get it to be around 30.And youre probably forgetting the payments on your 100k loan to your dad.
