Now in the last 48 hours I find myself in a total and literal quagmire. 

I know I can go through a lawyer but I was told it is a fairly simple process hence want to DIY.Regards,Xuming

I am considering other options to see if there are ways I can hire someone to just do showing only and mamage my own rent collection through Zillow app, I also have my own contactors to do maintenance but have been paying monthly fee to my property manager who has done literally nothing, they also never answered my calls.It definitely sounds like you need to reevaluate your relationship with your property manager.

Keep it simple is great advice.

december has one unit fully booked, 2 units half booked, and one unit that is virtually the same as one of the half booked units that has literally 0 nights booked (why?

It could be something as simple as a toilet running. 

For the folks north of 30% DTI, buyer expectation shifts are not meaningful because real qualifications just aren't there.The best case scenario folks-- dual income, no kids, no debt, have minimum 10% downpayment, sharing a 1br apartment under $2k in a average COL place looking for a $450-550k house is literally the only type of folk that is waiting for this "expectation" shift.
