I want to buy my parent's home that they are no longer living in as my first investment. I do not want to pay the comparable market value because I know what needs to be fixed. I want to know various options that I can do to buy the house and at the same time be fair to my parents.
You can pay for an appraisal or ask a REALTOR to provide a market analysis so you have an objective valuation, then negotiate with your parents from there.
You still need to evaluate the property to determine if it's a smart investment.
