Calculations for the scenario where you want to buy a place to live and then move out and rent it soon afterword (sort of a "house hack"). Calculates time to break even on transaction costs, expenses while occupying, expenses / cash flow while renting, comparisons with renting rather than purchasing, etc. There are some comparisons with 5% down and 20% down scenarios, though main analyses are with 20% since that's what I ended up doing. Details are in the comments on the spreadsheet. There may be a mistake or two if I missed something somewhere, but likely still helpful. Feedback welcome :-)
