Was this a dumb idea or a good one? I think its been about 7 years ago I had paid off my mortgage and wanted to redo a couple rooms so instead of borrowing $30,000 I borrowed $200,000 with a new 30 year mortgage at 3.25%.
I figured I could make more in dividends then in mortgage payments, and then after 30 years all that income would still be coming in basically forever.
Fast forward to today, having added a few thousand $ to this portfolio over the years either from money that I was gifted or months I didn't need to withdraw the interest I left it in there to grow. So all my deposits totaled $218,000. Monthly dividends/interest is between $1,700-$1,800. My mortgage payment (including escrow) is $1,605. So even with increases in tax and insurance, I'm still free and clear with this strategy and growing the account.
However, if I liquidated everything the account I'd have about $261,000. I didn't expect the value of the portfolio to go up so much. I owe $176,281 on the mortgage.
Should I keep with this as is? Should I sell everything, pay off the mortgage and still have over $80,000 in the account? Although I assume I'd have to pay some capital gains if I did this.
I thought I would benefit also from deducting mortgage interest from my tax return, but I don't make enough to itemize, I just take the standard deduction so it didn't help me in that way at all.
I had huge gains from IVZ, PAGP and PM - They went up so much the yield dropped below fidelity's mm rate. So I decided to sell some of those and then sold cash-secured puts at lower prices so if they drop I get them back at yields better than the fidelity money market, and if not at least I get the put sale income boosting over all yield. Some other ones like DOW and LYB have been terrible and not only dropped in price but significantly dropped dividend amounts. Still, overall more have gone up than down and have had more increases in dividends then cuts, I think.
I have 10-14 years to retirement depending on health, taking higher SS levels, etc.
Curious what you all will have to say. I feel like it worked out pretty well whether it was stupid or a good idea. Maybe I just go lucky and am a total idiot.
