<prompt> Human: I live in an expensive area where the lowest you can pay for a single family or townhouse is in the 4-500k range and I only make about 90k as a tech worker just starting my career. Im tired of living in apartments and renting in general, but 300k is probably the most I can afford on my current salary which is projected to go up of course so most houses are out of reach and I can only afford to buy condos currently. Im pretty wary of buying a condo because of HOAs and really that Im just tired of living in this style of dwelling. I was thinking of getting a house that costs more than what would normally be advisable and renting out a room or two to help cover things. How bad of an idea would this be? Id be buying a 4-500k house on a 90k salary, although this probably wont happen for another year or two since I have to save for a down payment and Id like to think by then Id be making in the low 6 figures. This is assuming Id even get approved for a mortgage of course  <response>: Youd need a very high level of savings to provide sufficient float to see you through times with no tenants, or disputes with a tenant. If you dont buy a property that naturally divides into houseapartment, be prepared to have trouble filling the extra space at market rates for an apartment, market rates for a room run a lot less.Having a tenant is a lot different from having a roommate, you might say ohh, their just roomies, but recognize youll have legal responsibilities to them.
