I purchased a raw land in Sep. 2005 only for the purpose of appreciation at $300K. And sold this land Sep. 2007 at the $310K. I have been deducted the property tax every year. I spent about $32K for the mortgage interest, and $4K for the mainenance. ( No improvement ) The maintenance was for HOA fee, irrigation fee, and Mowing & Spray. In this invetment, I got the appreication around $10K, and spent the $36K. My qustion is how to calculate basis and selling price in this situation.
