I think capital raisers who already have a deal would cut you in as an LP, and maybe share management emails, but I don't see upside in letting you manage my money, my loan, ultimately my deal. just my $0.02.If you have a local relationship with a lender, talk to them about what financing they'd offer you.

Anyways, I want to get into real estate as fast as I can(without cutting corners) to quickly build a portfolio.

Any contractor doubling their price for work done with permits is indicative of the corner cutting their original quote implied.

How much of that loss flows through to your personal return will depend on numerous other factors, so it is not a clear-cut yes / no.If this were just a single family home you were not renting, there is no depreciation.  

That is, aside from taxes and insurance, what are your numbers for vacancy, maintenance, cap ex/reserves, waste management, etc.?

You can waste a lot of time sorting issues out.

However, if you are acting as your own agent to buy or sell your own investment properties you would be splitting any associated commissions with your broker just like any other transaction, but the broker isn't getting a cut of your investment profits.

Dont waste time with quicken loans but shop around for rates.

(Measure 3x, cut once.)  

Calculate how much money you will be losing out based on them wasting your time and not moving-- that should make you angry enough to kick them out!
