As a foreign investor, I can get financing up to 80% for the purchase of real estate, so the biggest problem for a more serious project is down payment if you have a solution for down payment, please suggest me. 

Financing depends on your scenario and what type of property you're purchasing.

Purchase price: $125,000 Cash invested: $120,000 First try at turning a single family home into a duplex while going through the permit process for the first time.

I've found an off-market property that would require $175k purchase, $35k down, $20k in repairs, with a conservative ARV of $235k. 

Purchase price: $255,000 Cash invested: $51,000 Second property, bought soon after the first multi-family.
