The home is (I believe) a 5br/4ba, on a two acre wooded lot.

I had selected a floating, interlocking, faux wood plank vinyl flooring for most of the duplex, but had planned to put a matching carpet in the bedrooms. 

You’d also want the building to be wood frame to save money.

I've seen chain link right along a wood privacy fence.. all depends on what you have the cash to do. call your city to find out if any permits are required and ask about fence maintenance,, maybe if it's on neighbors land they can enforce a repair or removal. 

BUT - what if there are structural concerns with the roof, foundation, or wood destroying insects?

I'm trying to figure out best practices from more experienced investors and builder for constructing a high quality and low maintenance rental, so no better place to start then with the foundation.My question is,If you could build a portfolio of multifamily rental properties to hold for long term, would you build a slab on grade concrete floor (no crawl space) or standard conventional wood framed floor (has a crawl space)There are pros and cons to both but just hoping to get some people who might have other insight on it.

But I am just wondering if the flooring between the two story are wood base or Concret.

One is tropical elements are not friendly to many of the materials we tend to use here like fiber insulation and wood frames.

@Dave Charron I either Paint white because I like the farmhouse look it gives or I just do a nice stain on them to make the wood pop out more. 

I do allow pets in some of my rentals, but I have to say, they DO add to my cost, yet I do not charge a pet fee.Here is a list of things I have personally experienced a tenant's dog do.Dug out sprinkler heads pulled them off the lines.Yanked out sprinkler controller wires.Chewed off corners of interior doors.Scratches on exterior doors that looked like the XMEN Wolverine poster.Broke the lower portions of wood blinds.Bent or go THROUGH window screens.Yanked kitchen cabinet door hinges completely off.Removed 80% of paint off cabinet kick plates.Chewed off the bottom moulding of a refrigerator.Exterior door weather seal shredded to pieces.Dog poop all over the back yard when tenants agreed to clean up after each time.This is a new one this week - and I am still unsure how this could happen, can a dog's teeth be strong enough to put a dent almost a hole on the aluminum threshold of an exterior door?
