Hello!

I've been a Fool for many years, but this is my first post.
I feel I'm on target for retirement, but get different answers based on different retirement calculators I use. Basically, here's my situation:

Age: 40
Salary: $105,000, figuring 3% annual increases
Annual 401K contribution: max (currently $15,000)
Annual IRA contribution: max (currently $4,000)
Current 401k + IRA balance: $185,000
Investing risk level: currently aggressive
In retirement, I may work, but I want to calculate as if I don't have to
Social Security: Assume none
Current bad debt: 0.00 in credit cards, $13,000 car loan
Home Owner (Mortgage - Yes)
Real Estate investments: in 15 years, conservatively can sell or refinance to cash out approximately $300,000
Savings: $62,000
Probably need about 75% of my current income for retirement

So, I have 2 questions:
1) When can I retire?
2) What can I do with the $62,000 - anyone have a good real estate deal?

Thanks!
JB
