<prompt> Human: The house is 480k and I am being gifted 250k, I want to know how much I should put down and what I should do with the rest?The inspection is tomorrow but I already know the roof is about 25yrs old and will need to be replaced pretty soon - so probably another 10k-ish. Its a single lane driveway that Id like to open up at the end not sure how much that cost. A fence for my dogs around about .25 acres. The taxes are about 7kyr plus sewerage, gas, electricity, cable etc. Obviously I will put at least 20 down, just to avoid the PMI. I make about 4.5kmo. So I am looking for advice on how much I should put down and what I should do with the rest?Thank youEdit: I should have mentioned that the 4.5kmo is after tax and retirement contributions, and that my fiance should be brining in another 2kmo - hopefully this doesnt make it look AS bad as many of you have pointed outedit2: Ive gotten a lot of very good responses. I will answer some repeated questions:Yeah its in a HCOL area, a 200-250k house needs a significant investment to be livable where I live. I havent had the inspection yet but I have been approved by a lender for financing on the 480k house minus at least 20 that Ill put down without taking into account my fiances contributions - shes not on the loan. I will negotiate with the sellers on the roof with the target that they will cover closing costs, its not a given but possible. My general plan now is to put down 200k which leaves financing for 280k over 30 yrs at 4.375. Including tax, insurance and PI the monthly payment should be roughly 2050 utilities house maintenance maybe 2700mo total as ucatholicwannabe2 calculated for me.this is about 58 my net monthly income and 40 our combined net income.  <response>: The inspection is tomorrow but I already know the roof is about 25yrs old and will need to be replaced pretty soonWhy on earth are you buying this house? Youre still over 36 on income if you put the entire amount down. With taxes and insurance you better be able to eat those used shingles. This is a bad financial decision.
