I'd like to get into the multi-family space but will obviously need a larger amount of money to get a 20% down-payment for a more expensive property.

If you ask detailed bids for each items and look across multiple bids, you can confidently estimate the overall rehab cost.In general, the best practice is to pay the contractor across multiple payments - before rehab, during and after.

So I'm focusing on keywords like how much I put down for down-payment.

Buying a house with Solar installed on lease solar company wasn’t paid for 6 months by seller and is now refusing to accept back payment to reinstate the service and remove the lien.

I use zillow rent payments to collect rent for all my customer's properties and then forward the owner the rent minus my 10% commission. 

You buy a duplex and your payment is $3000.

That higher loan amount means your payment is higher.  

- How many payments can YOU pay out of pocket, in the case the builder “needs a grace period” or otherwise is unable to pay on time?

My real estate agent talked us up to $1.3MM, same down payment and 6% rate. 

I acquired this property with a 20% down payment and an 80% seller financing note with a 2-year balloon to allow myself enough time to stabilize it and get longer-term commercial debt on it.Over the last 7 months, I was able to raise the other 4 units to market rent and lease out the larger 5th unit to another state government agency on a multiyear lease.
