For Buyers: Like any significant purchase, the more information you have before submitting an offer, the better. Request Somerton Forge HOA disclosures, which will include the cost of the transfer fee, before submitting a written offer to save the hassle. If you want to split the transfer fee with the seller, addressing the issue up front will help.
For Sellers: Keep in mind the general range of what is considered reasonable costs for disclosure and transfer fees, so that if you are assessed a charge outside of that range, you will know something fishy might be going on. Also, remember that PA state has a statute that requires a timely response to record requests so that the sale of your home may not be unreasonably delayed.
