(I've used rentometer any other suggestions?)

I'd suggest 180 days.

Any suggestions?

Any suggestions are much appreciated.

They are lumping in my sister's personal debt (that was what the loan officer suggested) so we will only get $30k in cash to work with. 

You could use the words "suggested"  or "preferred" instead of "must". 

The neighboring units set the market ceiling in my market and they are more than happy to sit on their price, so I wind up stealing their tenants by being just below.I would suggest deciding up front on renovating or not, 100 year old structures do not support todays lifestyles unless they have been updated, so you will pigeon hole yourself to the lower renter.
