That puts us in line with other developments in town, hoping to run into some good deals on the materials that we're flexible with.

Usually, the terms are worse than if you could get a conventional loan but they are very flexible.  

I checked the crawlspace out a little further this morning after posting this and previously they were venting it to the outside but for some reason they uninstalled it running to an outside wall and just ran some flexible duct straight down under the crawlspace.

Many passives work 9-5 and don't have the flexibility to do everything that is required to purchase and operate a MF property.

SFH's are more flexible in the long run.  

I  currently work at a hospital as an operations manager but I am looking to find something more flexible so that I can do real estate investing.

If they sounded flexible then maybe say something like, "So your negotiable around X?"

Im looking for something longer term if I can get it but I’m relatively flexible. 

I agree with @John Warren, you can still get a low money down conventional loan (in the process of using one myself for my first deal) which will most likely be at a slightly higher rate than an FHA loan but more flexibility when it comes to what you can buy and where.

That is a flexible amount of time depending on the bank, but if someone takes out an "owner occupied loan" and never moves in, that is probably mortgage fraud.
