@David Naphy With a strong credit score you can do better than 8% on a DSCR based cash out refi today. 

Your best advice would come, for a Tax Advisor NOT a Tax Preparer (CPA).

We also got over 100K in credits for repairs.It was a killer deal.

You definitely want to use a thorough screening method like rentprep.com that gets their income, credit, background check, and call at least 3 references (make sure to verify them by address/job and then their name).  

What is your credit score?

Most of the lenders I work with (provided you have experience and a credit score over 660) would do up to 85% of the purchase price and up to 100% of the rehab costs, provided this doesn't exceed 75% of the ARV.As for the idea of selling the land, great idea.

To answer your questions here though:Alternative options - I was going to sell all my stocks and etfs, take out a HELOC, and some credit cards to try to shoestring together enough to the deal without a hard money loan. 

Alternatively, if the bank ( assuming there is a bank) is fine with it, you could negotiate a credit and escrow the funds to be released after you do it yourself.  

For a $300,000 property it could be $30,000.Then, do you have that much cash or credit available to you, in the event of a Due on Sale call?

That way, you might preserve some of your monthly profit while still knocking out that line of credit.
