We also have many unique buyer incentives where an investor can get up to a 10% price reduction to come into immediate equity, or get that 10% as a cash back at closing to reduce your down payment and increase your ROI, or buy rates down into the low 4s on 30yr loans to maximize cash flow.

@Duarte MarquesPossibly but highly not recommendedFor those with no real estate experience or experience in taking on debt, it’s not easyTo do it also with little to no down payment or reserves in most occasions will end in disasterReminds me of when in high school a friend used to let his dog drive his car.

You should find out what percentage of the rent is being paid by S8 and by the tenant.Tenants have to sign the rent increase and some won't because they don't want their payment portion increasing.It's also highly unlikely a S8 office will approve the huge increase from $797 to $1300.- BTW: the $1300 includes all utilities being paid by the landlord.

I am thinking about taking out 5 to 10% to fund a down payment on my next live in multifamily house hack.

I'm looking to invest between $50k and $75k as the down payment. 

The mortgage payment is $1,000 on each house, so you earn $500 per house or $2,000 monthly.

During construction you'd have minimal payments, either IO or accrued.

What would standard down the payment be? 

For example, the buyer, if they find problems with the property or stop making payments, can blow up the seller's credit.

A $100-$200k down payment would get you a decent multifamily property, possibly with land depending on where you look.
