Are there any options for lower down payment loans in general or even for college students?

The guest is always right, even when they aren't.

One, I made a profit; other one, I kinda even out. 

Even then, I’m bringing in $81,000 a month.

That's the reason there are so many fourplexes and so few fiveplexes or even sixplexes.From what I gather, post offices and utility companies rarely care much about the permitting/zoning issues, so it probably wouldn't have been hard to get those set up.

If you can buy a fixer in a great area, that's even better.

Also, focus on 2 years of job/income stability.Class D Properties:Cashflow vs Appreciation: Typically, all cashflow with little, maybe even negative, relative rent & value appreciationVacancy Est: 20%+ should be used to cover nonpayment, evictions & damages.Tenant Pool: majority will have FICO scores under 560 (almost 30% probability of default), little to no good tradelines, lots of collections & chargeoffs, recent evictions.

But if I put the money into buying a house, with the leverage of a mortgage loan, I can still earn about 11% annually on my investment on the appreciation, even though there is no cash received for the rent.

If you have other money to grow your portfolio even with $107K left in the property then  hold the property. 

I've included an example below to help illustrate this.So different lenders have different rates (which do vary even for DSCR loans) but these are factors they all consider.See example below:DSCR < 1Principal + Interest = $1,700Taxes = $350, Insurance = $100, Association Dues = $50Total PITIA = $2200Rent = $2000DSCR = Rent/PITIA = 2000/2200 = 0.91Since the DSCR is 0.91, we know the expenses are greater than the income of the property.DSCR >1Principal + Interest = $1,500Taxes = $250, Insurance = $100, Association Dues = $25Total PITIA = $1875 Rent = $2300DSCR = Rent/PITIA = 2300/1875 = 1.23If a purchase, you also generally need reserves / savings to show you have 3-6 month payments of PITIA (principal / interest (mortgage payment), property taxes and insurance and HOA (if applicable).
