ok some quick math if I want to be objective over the next 25 years, so your financing 500K by my math, and over the next 25 years, you'll pay 690,000 in payments or 190k in interest if rates stay the same or $633 over the life of the loan on average. 3500-2300+633 = 1833 over the life of the mortgage. but today and the first 5 years your interest portion will be over $1000 so 3500-2300+100 = 2200, which is almost the same price as the fixed costs of owning a home. but some other factors to consider, special assessments risks of ownership, and how long you plan on living there? because if you plan on selling within 5 years and upgrading you need to factor in real estate fees, so let's say 15k of fees and commission to sell ( it's probably over 20k) over 5 years is 15k/60= 250 so now 3500-2300+1000+250=2450 if 20 k closing costs (like more than 2% commission 3500-2300+1000+333=2533

​

so lots of hidden cost ownership. so right now if you started just saving the 3500-2550= 950 a month instead of a mortgage and investing it you'll be making more money for the first 5 years. with your down payment plus the 950 per month contributions, you'll have made an additional 25k of returns at a rate of 3% so youll have a lot more equity. and flexibilty
