In a seller financed deal is 5% or lower down payment common?

I understand this may not make a ton of sense because its higher level stuff but the a great book to check out is "Landlording on Autopilot." 

Tried to explain to one that some -not all-agents don't show listing with lower buyers commission and he wanted to argue with me about it was our fiduciary duty to show all. 

If they specifically need to cash-out to buy another home than seller financing is often DOA.As mentioned, if the have a balance on their underlying mortage- If they want to pay it off it might require a big downpayment- It is possible to leave it in place with a Wrap but that is an advanced strategy and while fairly low risk, the due on sales clause is a concern.On interest rate, my experience is that a seller finance buyer usually has to pay a few points above the going interest rate for conventional/FHA lending so probably closer to 7% these days although it never hurts to ask for lower...All of this is theoretical so the advice to chat with seller to get more information is the right next step.Jeff

"or pay someone else to do it more efficiently"Not criticising simply pointing out that sending notices is kindergarten level landlord responsibility that every reasonably competent landlord should learn to do.Yes if someone want's to hire a demo crew to take down a curtain rod by all means do so.

They will go max $100k or 70% LTV whichever is lower.

My area of uncertainty has to do with the lower quality property in a lower income neighborhood.

It depends on the level of the broker and their network.I have thousands of commercial retail property owners built up over the 15 years in business nationally.

But if I can guess here a little...FHA loan will have a significantly lower down payment for a multi-family unit - 3.5% down.  

Rent increases are based on market comps and if the rent currently is more than the market comp it can be lower.
