In my opinion either way is fine, but if I were you, I'll use a chunk of my money due to your lack of experience, to save on borrowing cost and also to mitigate your exposure should you run into delays or budget overruns 

I don’t have any debt but my main home, but I don’t think I can be approved to borrow much more. 

The disadvantage is you now have interest you'll be paying on the funds you are borrowing.

I like the control of owning it, plus borrowing against equity, it so nice, but I can also relate to all the copper thieves ruining your week so they can buy two hits of meth.

@Devin Meriwether You will likely not find a Hard Money Lender in this day and age who will find a purchase with 0 down especially if you are a new borrower with no investing history.

Cash for the land and then borrowed the rest from an investor I've sold rentals to, I was suppose to be a 4 month project max but it went under contract and fell through 4 times so took closer to 6 months but he didn't ask for much- just to cover the interest he had from taking it from a line of credit for >6months.

This is not required, however, since there are other ways to ensure the loan is for a business purpose loan.A wise lender will always ask the borrower to document what the money is being used for.

Only reason I'm mentioning is I do a good amount of construction financing, and even many of my 'bankable' clients will use private money b/c it's tough out there trying to find construction financing even if you're very solid borrower, which it sounds like you are. 

For example, a lender might offer you 85% LTC (loan-to-cost)/65% LTV (loan-to-value).Interest rate: What will you be paying to borrow the money?
