Keep in mind it's not often you can make $150K in 2 years in any real estate deal like your BF did.One plus I see is that the intersection you name is fairly close to a new light rail line.

I have a degree in accounting and do a fair bit of tax planning and preparation too.

That should be fairly easy for you.
