Does anyone know if I can prepay my property taxes due to San Diego in April 2018? I have an escrow account with my loan servicer.[/quote]
You definitely can pay it in December.
Send your 2nd half property tax payment directly to the county (not to your loan servicer)
(In March/April your loan servicer will send the same payment to the county, it will get returned to them and you will have an overage in your impound acct.
At a future point there will be an overage in your impound acct and it will get refunded to you)
As far as prepaying interest, it is tricky because the accounting systems are all automated,
Just because you make your January payment in December,
it isn’t due until January 1st.
The 1099 that loan servicer issues for 2017 interest paid may not reflect your early January payment.
SK can confirm, but paying your 2nd half property tax bill is an acceptable deduction for 2017.
