In the winter the snowbirds flock here to rent for a few months and then move out just in time for spring breakers on through the summer families and then the holidays.  

A new roof in this case would be a deal breaker for me if not done. 

That last condition is a deal breaker for us.

Just 4 breaker boxes!

Being dated in this area isn't a deal breaker, but they should be in good condition. 

Credit card companies are FICO's #1 clients), that can qualify now that could not previously qualify.There will be times where the trended data is a deal-breaker for Fannie, and for some reason they can't go Freddie, but these will be rare.I sincerely doubt it will ever impact a deal where our FICOs are north of 700.Interest rate pricing differences between Freddie and Fannie are very trivial (or people would notice reeeeeallly quickly when I did my "switch it to Freddie" solution, right?).

We put in a new AC unit, breaker box, roof, tore out rotted wood on the roof of the back addition, new insulation in the back room, new windows all around, all new doors, new siding, collapsed the septic tank and added a sewer line to the street, moved walls and opened walls inside, tore out the rock driveway and poured a concrete driveway, new fencing front and back, we also replaced some of the old steel plumbing with pex. 

I think the grass is an issue but having a vacant property AND maintenance issue would be a deal breaker for me.  

This will make the last unit viable.Minimum drawing requirements include, but are not limited to:Bear the seal of a register design professional, in compliance with Sections 33791.01, 4703.12, and 4733.14 of the Ohio Revised code.Plans shall be drawn to scale and shall be sufficiently clear, comprehensive, detailed, and legible so that a determination can be made for conformance with all of the applicable provisions of the currently adopted codes.Mechanical plans: unit types and sizes, system layout, ventilation requirements, and provisions, and control system diagram.Electrical plans: riser diagram including provisions for grounding, panel board schedules, lighting plan(s) and circuiting, power plan(s) and circuiting, and special systems plans.Energy calculations.Provide a site plan showing to scale the size and location of new contruction and all existing structures on the site, including setback and side yard dimensions, all property and interior lot lines, distances from lot lines, the locations of the nearest streets, the established street grades, types and sizes of all utility lines and the elevations of the proposed finished grades; drawn in accordance with an accurate boundary line survey.Submit plumbing plans and details that locate and describe all fixtures, fixture schedules, and show compliance to handicapped accessibility.

I see, I am trying to figure out if there will be a tie breaker if all else are equal other than locations.
