Every year, in California, your property taxes increase 1%, water doubled and tripled in the past few years., the prices for materials and contractors has more than doubled.You are running a business and it is not about being generous.

You are only putting 5% down so your loan amount is much larger and therefore your mortgage payment.Cashflow is tough when you move out because prices doubled since 2015 (at least in Colorado Springs) and interest rates have tripled in a year.

Hard money is expensive, though, so you want to make double and triple sure that you will indeed be able to refinance.
