<prompt> Human: So, after finally finishing with school, I now have a job as a high school math teacher. Hooray! I am 27, making 45,000 per year, I have paid off my debts and am starting to save money. Here is my precise situation. In the fall, I am interested in purchasing a home. I am planning to do a loan through my credit union in which I put 10 down but do not pay PMI the extra 10 is considered a second mortgage. I should personally have about 27,000 in savings by then, which I hope to allocate as 18k down payment on a 180k home, with 3k for closing costs and 6k emergency fund. I have an aunt who is willing to co-invest on a property with me. If we co-invest then I could most likely look for properties for about 250k, which would ideally give me the extra funds to have an extra bedroom that I could rent out. Pros:-The renter would likely offset costs enough that most months, I would come out ahead compared to the less expensive home-If home prices go up, greater benefit from a more valuable home-Option of buying my aunt out of the home in 7-10 years if I can afford to do so Cons:-Any months without rental income would be expensive-- as in, 50 of my 3100 take-home pay. I DO think I can afford these months since I am budgeting 500month for savings, but, these months might be pretty tight financially. -In 7-10 years, if I could not afford to buy my aunt out of the home, I would need to sell the property. Im not necessarily opposed to moving but if prices drop during that time then I could be at a financial disadvantage. Thoughts?  <response>: Personally, I wouldnt do the coinvestment. Buy what you can afford and focus on that.
