Even in a mediocre market, if you have a great agent and a great PM, you will outperform a great market with a mediocre PM and agent.That's also why I think it makes no sense to invest in 17 different markets: you don't know much about any of them, you have to build a network of people in every market, the law is different in every State and it's physically/economically impossible to visit any. (1-4 units anyway, large commercial is different). 

What are my options to cover the $100k difference to still get this house with 0 down?

People think that's even different for investors...the fact is, it isn't.

Hard for me to get to specific as I'm not super familar with the market in your area however one thing I'd say is also take a look at modular homes as there is a fairly significant difference between a modular home and a manufactured home.

It doesn't cost anything extra, laws may be different where you are.

@Rollin BuffingtonYou will want to speak to an accountant since, if the current owner of the property and the owners of the LLC are different, taxes might be owed when the property is transferred/sold to the LLC

What that looks like is different for everyone.Once you have enough you want to outpace inflation safely.

I'd say find a different broker / lender that knows the right product to get you into at way better pricing. 

It is not really any different than then starting a construction company, a plumbing company, a marketing agency or a tech company.
