You may want to consider working with your accountant remotely to expand your options.

RUBS seems like another easy idea that we'd have to calculate monthly, costs me nothing, and does a fair division of the bill based on the number of people per unit.

A good broker can communicate between multiple lenders and often times has established relationships within the C-suite levels of multiple lenders that they can make calls on your behalf to "shake some trees" and get things processed not just in a timely manner, but in a manner that is on time based on what you are trying to do.Unfortunately it is not uncommon per se, but knowing where these hang-ups tend to happen and how to time everything based on lenders timelines and processes is where it can be helpful to have 'go to' lenders that you are familiar with, and they are familiar with you to help get things done.Good luck though, happy to help where/if I can.

Any other options people can think of?

I know this isn't the path everyone would choose, but it seems like AN option to me.

What type of tenant base are you looking for? 

A good realtor can also introduce you to mortgage brokers or financing options that suit your needs. 

Often times with wholesale deals, speed is the name of the game, so taking time to conduct lengthy due diligence is not an option.

We will likely sell the house when the current tenant moves out so leaving the holes (even filled) is not an option. 

What are the best options i have to counter this?
