<prompt> Human: My house is worth roughly 170k. My home is 3 bedrooms 2 bath and easily rentable, it should rent between 1050 and 1150. On my 30 yr mortgage Ive paid 80k and still 21 years left on loan at 4.25 apr. My wife and I make approximately 90k yr combined. Currently, we are investing as much as possible to get our home paid off as quickly as possible. If we keep paying off our home at this rate considering no financial changes it will be paid off in 3 more years. Financially, we could get a second house with renters and still continue to pay for initial property quickly. We would like to have the ability to retire earlyer or at least have a sizable investment for our futures. Ive considered 3 situations:1. Continue paying off house quickly and continue living in current house indefinitely assuming work situation doesnt change continuing to saveinvest as much as possible after home loan is paid off. 2. Refinance home at 90k with new 30yr refi loan. Rent property and purchase 2nd property. I dont really understand how the depreciation of the property including new home office and deductions of other things like advertising and repair, cleaning etc of the rental property would affect my income. 3. Same as 2 just dont refinance.  <response>: Consider first and foremost all of the effort it takes to legally rent out and maintain a house up to code, and determine if the headache is worth the extra income. You might not even get paid for large amounts of time if you cant find decent, reliable tenants.
