I want to get to a point that I am comfortable with the units I have (i.e. they are the right ones, in the right quantity, and will provide sufficient income when paid off) then work on paying them off. 

If the repairs are of a quality to bring in sufficient rental income..

Given the very recent purchase, is it sufficient evidence to provide the final closing disclosure at the hearing?

Multis are incredibly rare with incredibly high demand, you just won't get an offer accepted being at that bog of a competitive disadvantage.Also with FHA, you wont find a 4 unit in the area that meets the FHA self sufficiency test if you use a low down payment on it.

Are you using the baseboards as supplemental heat.If not are you running these units in the north at all and do you feel the provide sufficient heat alone during the dead of winter.

If the demand provided to the requestor shows that upon executing the sale, funds delivered won't be sufficient, then someone has to come up with the difference.

In particular a individual that is not self sufficient or responsible.

What the IRS does stipulate that all activities of the plan must be for the exclusive benefit of the plan beneficiaries.The IRS recommends the following criteria to determine if a plan’s policies are for the exclusive benefit of the plan participants: The cost of an investment must not exceed its fair market value (FMV) at the time of its purchase.A fair return commensurate with the prevailing rate must be provided.The investment must be sufficiently liquid to permit distributions per the plan terms.The safeguards and diversity that a prudent investor would adhere to must be present.So put that in perspective relative to the lending arrangement you are considering.

Operate a safe business with high standards, have sufficient insurance and you will do fine.

My policy is that I generally do not charge a tenant unless I have sufficient, documented evidence to win my case in court.
