@Brad Hassett -I believe he's referring to your debt to equity ratio, which is common in any business that uses debt. In my experience the bank will be looking out for you on this, on most investment products (example, you need 20% down/equity in a property, aka 5/1 debt to equity). If it is your primary home however, you may be able to exceed that, and he is advising you to exercise caution when doing that, in case we incur a significant economic correction.
Home value: $550,000
Loan amount: $280,000
Equity: $270,000
Current interest rate: 2.75%
Mortgage payment: $1,600
Current rate payments: $2,650
Given that information, what you both do?
I am not understanding the mortgage payment/current rate payments numbers given above but:
If it were me, I would consider a loan to value of 75-80%, and pull out 132,500 to 160,000. (Id probably be at 150k because its just a nice round number :) ).
If principal and interest on $280k at 2.75 over 30 is $1143, and $150k @ 3.75 over 30 is $695, now your PI on both is $1838. If you can achieve a conservative 8% cash on cash on that 150k, your net is $305($1000-695) a month on that money, plus the depreciation/tax benefits and principal paydown on the new property of course. Your numbers on the existing mortgage may be slightly different, but you get the point.
