0% down? That's a loaded question lol, plenty of ways to do it though.
USDA and VS are 0% style loans (but you pay closing costs).
But If you're creative with the finances, you can technically make any deal 0% down.
Here's a perfect example of one deal I just closed with one of my clients a couple weeks ago:
Style: Triplex - (Found this one off market for my client, which works best because we have more negotiation power vs a market listing with multiple bids)
Price: $389,000 Taxes: $11,950
Interest Rate: 2.5% Loan Type: FHA
PMI: $320 per mo Insurance: $100 per mo
Total monthly mortgage cost: $2900 per mo
it was a 3x 3 bed 2 bath, so each respective rent was $1500 per mo (extremely undervalued rent for the area btw, we're gonna increase it to $2200 when renovated).
So mortgage = $2900 - Rent of $3000 = -$100 (or $100 per mo rent cashflow).
My client was basically getting paid $100 Per mo to live in the 3rd unit.
Now the best part, the downpayment and closing costs: $25,000
How did we do this? I had my client take out a loan on her 401k, then had the seller offer a $25k credit at closing so my buyer could pay back her 401k Loan.
So basically, 0% down, 0% mortgage payment, and when she's ready to move out she'll be looking at an easy $1600-$3700 per mo in cashflow.
This is one of my favorite strategies to employ.
Hope this helps.
