Do I need to lower my standards or try to find alternative ways to source deals? 

Given our size and visibility, great responsibility is taken to ensure everyone follows shared standards that balance the best interest of sellers and investors alike.

If I can break it still, what does that look like, and are there standards on kinds of concessions for having done so (like giving them 2 months to find another place, those 2 months on my dime, etc.).  

You are overestimating these numbers.Speculations as to why: tenants in these particular rentals may be tolerating a lower standard of maintenance than you think and thus everything wears longer than you think it will, I may have a different relationship with my maintenance people than you do (actually I don't let my management company do anything and I'm very involved in maintenance, I know how to do practically every necessary task, I manage people directly and sometimes I'll do a few things), there may be an error in your calculations such as you're assuming two units in a duplex don't share as much as they really do (they still share roofs, yards, and many other things), or something else entirely.Either way, your numbers are way too high and I will not be able to answer why in more detail or provide you with my exact numbers without spending a significant amount of time on this. 25% ain't too far off. 

Sometimes different title insurers have different underwriting standards and one may agree to insure while another may not under the same circumstances. 

As there is no cashflow during this period this may not be an ideal scenario for everyone but we are all cash buyers building out a portfolio that will provide income to keep our current living standards once we retire from our day jobs in 5-10 years. 

I don't think most sponsors understand the legal implications and unfortunately it's been 15 years since a cycle has caused the tides to go out, so very few do but once these issues go to court, judges will hold sponsors to a much higher standard.

That probably means sellers will more often rely on the X% that folks vaguely believe to be the industry standards. 

FHA does not have a clear definition in their guidelines, but most lenders have stability standards, depending on several factors (contract length, previous employment, etc).

I also just completed the new on site laundry facility and opened it up.
