The following link will take you to the VA's manual and the section that covers what is counted as income for the purpose of VA Pensions. Look down the table of contents for 'sale of property'.
Improved Pension – Counting Specific Types of Incomehttp://www.warms.vba.va.gov/admin21/m21_1/mr/part5/subptiii/ch01/ch01_seci.docThe following information is from the Code of Federal Regulations and discusses 'profit from sale of property'
38 CFR 3.272(e) Profit from sale of property. Profit realized from the disposition of real or personal property other than in the course of business, except amounts received in excess of the sales price, for example, interest on deferred sales is included as income. In installment sales, any payments received until the sales price is recovered are not included as income, but any amounts received which exceed the sales price are included, regardless of whether they represent principal or interest.
Hope this information will address your questions.
