Here let's start with the basics :
Purchase price of said house is $ 3,000,000.00
You plopped down $ 1,000,000.00 ....
Financed the bal of $ 2,000,000.00.....
What rate are you at ?
What is your Net Income ?
What is your Gross Income ?
What additional expenses have you " saddled " yourself with ?
( Cars, Planes, Boats..Etc...)
What are your monthly basic living expenses ?
Are you self employed ?
( If so, do you purchase thru an LLC or by " Personal. )
or
Are you employed ?
Are you married ?
Are you claiming your " Spouses " income as additional ?
Do you have savings ?
Do you have kids ?
Hypothetically we will go with the " Low " rate to date of 3.5 %
Financing $ 2,000,000.00 at 3.5 % = $ 70,000.00 annually
With the Principal diminishing each year the amounts change
Now we will assume you do it for 15 years
You state your monthlies are $ 7,500.00
( Is that one House, 2 Houses, 3 Houses, Houses + expenses ? )
You see " Messy " your numbers Just don't add up.....( See Below )
...........................................................................................
What is your " Credit Profile "..?
We will assume it is 720 or above ....
At 15 years your monthly would be $ 14,580.98
Your interest would be $ 573,577.15 @ 15 years
Your total paid would be $ 2,624,577.15
@ 30 your monthly would be $ 9,264.23
You need to explain your " Messy " Math " Messy ".............
I'm being Very Very Polite here " Messy "..........
