You might put down 10-20%, which can be easier to manage compared to traditional financing.A motivated seller can be open to different terms, especially if the property has been sitting for a while, so just be creative and make sure the deal works for both sides.

You need comparable sales and there are typically not a large number of 4 plex in close proximity.

A simple 5% return per year gets you $50k/year...and you still have the $1M to adjust to inflation by reinvesting into different vehicles along the way.Focusing on taking the long term returns ($$$/year) can be a better choice, but you have to look at the long term impact with all your options, compare them, and then make a choice.Do you think they teach that in school now?

Then the Disney area may be a good fit.But if you watched some youtube channel with someone, who seems to get a deceitfully large percentage of their info from selling courses, preaching the dream of massive upfront cashflow that you can then leverage into another down payment next year and so on while exponentially increasing your wealth so you can quit your job and live on the beach in Aruba, Disney is the wrong market for you unless you're willing to invest substantially into super tippy top end theming.The good news if you're in the former camp is that prices have come down quite a bit here compared to most of the country with all of the saturation/competion. 

Also show market analysis of both inventory and rent rates compared to your plan. 

Disclosure: I have only done this with MFR properties but according to the state it should be acceptable with SFR property as long as you claim holding it solely for investment and not your personal residence as you would already get a better deal.A few other slight perks of SC compared to some other states is the taxable value is not retroactively applied.
