It all depends on the client base, property details and your comfort level.

Obviously I think for the most part you can go based on the coverage level on the box if it gives it.

Depends on your comfort level with risk too.  

After you have more experience and have a certain comfort level you can go for off market purchases. 

If you're buying a house, just go buy it and ask the seller to take 3% off the price, or allow them to keep the extra 3% to sweeten the deal...If you're selling your flip or whatever, there are plenty of vehicles that allow you to safely do so and offer varying degrees of assistance depending on your experience and tolerance levels.

If I can rent both levels it works, but only the upper level has a rent-ready apartment.The bottom is 95% open space (think large chapel). 

Our building had dropped about 4" on the east side so our contractor had to raise the floor (like raising the dead) to make it level for the Luxury Vinyl Tile.The final deal was over double our original budget. 

Picture a positive loaded attribute property; good tenant class, safe place, good appreciation etc etc, that area is going to cost more if not most and have very fierce competition on multiple levels because it is loaded with positives.

I have Recently hired a new property management team and I am becoming very worried about their level of care and communication when it comes to my properties.

So we were going to add a sun room off the side of the house, problem was when I was in the basement measuring where to punch the mechanicals through we kept coming up 10' short of the outside foundation at ground level.
