600k is that too much for a first time investor?

[Collin WIlkinson]

I found a deal that has potential for a lot of profit. I am having trouble finding financing.

It's a large house and a great lot.

4750 square ft

3 bed 3 bath

2 acre lot about 30 minutes from Denver with an incredible view.

I would like to frame in a 4th bedroom.

The house needs about 80k worth of work. I've talked with a couple agents and I want to offer 500-520k. I do believe I can sell at 700-720k

I do not have the property under contract yet.

Is this too much to bite off for a first time investor. Any ideas on how to get it financed?
