Can not afford to pay 2nd Mortgage-
Whether or not they could repossess your pool depends on on how
Whether or not they could repossess your pool depends on on how attached it is to the property. If the repo men cannot remove the pool without causing serious damage to your property then they'll just go to court and get a lien on your house. Trust me, having a lien on your property for back taxes is MUCH worse, 'cause the government doesn't need to go to court to impose one. And the more liens you have on your property the more your house will go down in value and the harder it will be to sell it.
Foreclosure is tricky with second mortgages because it's second in line after the first mortgage. If the second mortgage lender forecloses they're going to have problems getting possession because of the first mortgage. If the second mortgage joins the first to the foreclosure (and every lender I've seen joins everyone they think has an interest even if they're dead. Seriously. I have seen dead people being foreclosed on) then the second lender would have to wait for their money until the first lender and the back taxes have been paid and may not get anything. The best thing I can suggest is to try and work out new repayment plans with both your lenders or consolidate your mortgages.
