You could get a DSCR financing on the 1st rental property you have to come up with funds.

They may be able to finance you at a low down payment if you have experience, reserves, and FICO as long as the 65% of the value can support the entire purchase price 

Get financing.

As you know wholesaling is illegal and no attorney in their right mind will close these going forward.The installment contract is where you are buying the property with owner financing.

There are markets in the US though where deals look like:Purchase 80kRehab: 60kARV 190kIf you have good credit you should get 85% financing on 80K, your down payment is 12k, and the 60k will go into escrow for the rehab so you will need to front the contractor money to get started and unlock rehab money. 

Essentially I am finding and procuring the land/lot via traditional financing and funding everything through the development phase until we get to Construction Loan. 

If you want to use leverage 2-4 units probably gives you more financing options and also widens your pool of buyers for exit strategy. 

But mostly owner finance deals.  

Or private equity financing? 

So they would want the plans approved, and budgets complete with GC contracts before approving the financing, then once approved they will want site work and some foundation work funded by the sponsor before their money kicks in.
