You have bills to pay and if they promise you your money by a certain time each month, then you should be getting it.

Can these be tax write offs (home office, phone, car expenses, etc) even though I won't technically be making money for some time until everything is completely built and leased?

There are several apps that will report credit lines to your credit report without getting you into debt.One is called "Self": You sign up for $25 a month for 24 months, it reports to your credit as an installment loan... the kicker is that after the 24 months they give you back most of the money that you paid in.

Money is good, consistently pull-in say $150-$200k although being extremely busy with very long hours.

If the mortgage is not paid the first position mortgage gets 100% of their money before the 2nd mortgage/HELOC sees a penny.

If the agent won't give you the money back, talk to their broker and then go up the ladder from there.

When we loan money, we are betting on the person we gave the money to.

Have the money ready.2.

If you hear "easy, fast, with no money required" - be cautious. 

I'll try to respond to each component of your comment:- My idea of using an equity partnership as described above is coming from Brandon Turner's book "Investing in Real Estate With No (and Low) Money Down," and in the chapter on partnerships he goes through various why someone with cash may want to engage in a partnership.
