If they are VERY professional, they will have their processes in writing as verification that policies are enforced equally and fairly by their entire staff.6.

So long as each LLC does not own more than two residential dwelling properties, or more than four dwelling units total, the LLC may require two month’s rent as security deposit.Although elsewhere I have expressed the opinion that placing each rental unit into its own LLC is maybe not necessary for limiting liability, if an investor is subject to the new security deposit limitations, the idea of limiting the number of dwelling units in any LLC to four rental units, now has an added benefit of allowing the LLC to require higher security deposits.Below is the pertinent portion of the statute:(4) (A) Notwithstanding paragraph (1), a landlord may not demand or receive security, however denominated, in an amount or value in excess of an amount equal to two months’ rent, in addition to any rent for the first month paid on or before initial occupancy if the landlord meets both of the following requirements:(i) The landlord is a natural person or a limited liability company in which all members are natural persons.

Quote from @Daniel Mendez: My policy is to set standards and apply them equally to everyone.

Your tax deduction equals the interest that you actually paid each year.

However, if I lived in the units, the total rental income would equal $850 leaving me with a monthly payment of $350.

I'd say for the long term, a duplex will be appreciating more than a SFH (all things equal).

Many will go into bankruptcy, people will be laid off in droves.I was visiting Thomas Jefferson's farm in VA a few weeks ago and learned that while he wrote "all men are equal" into the Declaration of Independence he also had 650 slaves working his lands.

Assuming the property is equally owned 4 ways (25% each) you could have the property appraised for confirmation of value: $1.8M/4 = $450k/share x 3 = $1.35M could be obtained as a cash out refinance, potentially utilizing a healthy portion of the STR or projected STR income to qualify. 

Keep in mind it probably won’t be an equal split, because the person with the money is taking most of the risk.

Not all Jumbo, DSCR or zoning types are created equal.
