Items to consider when selling a houseYou may pay around 7% to 9% of the value of the home in fees(Realtor Commissions, Title costs, Title Insurance, Stamps etc).The sale may also result in taxes(Federal taxes + State Taxes).You might be able to avoid taxes by doing a 1031 exchange or QOF Fund.You no longer have an asset that can potentially provide you cash-flow / appreciation.Do you think you can make up the 7% - 9% in fees + Taxes over time by buying another property?
