I would guess less than 1% of deals are seller financed - and most of those are still done with 20% down.

You can purchase this with a low-money-down FHA loan. 

If you want to develop it, I can refer you a lender that will lend on a completed subject to appraisal but you'll be limited if you just want it for the lot.If you simply want the land as part of your property, you have more options including a HELOC which you can still use for development down the road. 

If someone is walking down the street and trips on your sidewalk or a  walk way whether its a tenant, delivery person or passerby you are the one who gets sued because its premises liability exposure.

You also wouldn't want to create a cloud on the title, so doubling down and working with a legal professional/attorney would be best advised. 

I'm not factoring this in right now, going based on the numbers I see.Definitely able to put down additional funds to be creative with a lender, at the numbers you are thinking. 

And hands down the #1 violators of tenants rights (I mean legit cringe stuff) are those large communities, not investors like those who make up the majority of BP. 

The SST doesn't apply for legal 2-flats so if you want to use FHA it's probably better to target those that maybe also have a non-conforming basement or attic unit.This is why the 5% down conventional loan is a game changer for house hackers.

There's many ways to get into a deal with low to no money down!

Step 2: Narrow down your "buy box" (are you market-indifferent, are you looking for a certain level of cash flow, etc.).Step 3: Connect with real estate agents and begin making offers!
