What brand/manufacturer do investors typically prefer for new manufactured homes? 

My advice would be try and find a reputable investor friendly Realtor in the area 1st and foremost.

It sounds weird, but you have to be careful how much you advertise so that you don't get a reputation for being "out of money", while at the same time networking with wealthy individuals/family offices/private equity.It's a little different if your approach is going to be only loaning your own capital.

We have to keep in mind flippers have a bad reputation of doing the bare minimum and making loads of money (which we know isn't true).It would be hard for me to recommend remodeling it without spending more time on it.

I'm a Radiographer In military manufacturing and put together a budget so within a couple of years I want to take the jump into owning a property and renting it out.

Are there any comparable and reputable companies like this I can reach out too?

Reach out to the resources provided and reputable community leaders.

Any reputable recommendations from you guys?

There is positive population growth, tech and manufacturing (Tesla, Google, Apple) moving to the area, and low property taxes.

So knowing scope would help narrow down on risk mitigation tactics.I guess at the end of the day, it all comes down to knowing what is needed, order of operations, and having as close to true quotes from reputable contractors in hand.Beyond that, really knowing all that is needed and having those extremely detailed scope of works for each trade before you get your bids.
