In reading the various tax proposals, it appears there is an effort to eliminate interest deductions for 2nd residences. If this passes, then no doubt it will affect boats , RVs and of course condos. This deduction is hyped to encourage potential buyers to break out their wallets. There is also mention of removing the deduction on home equity loans.This would apply to not only new boats as well as used boats. In addition, personal property taxes are also mentioned which would add to the new equation where boats are subject to the a personal tax. Seems as this will not only affect new boat sails but hit the market for used boats. On a brighter side it may affect new condo construction.
