I have a 4plex in las vegas nv that I purchased last year, it has a community laundry room.

Closed and am all good, used the new 5% multifamily product that came out last November 

I would think a lender views the STR as a higher risk simply because a long-term tenant has a defined lease in place, that is usually 6 months or more in duration.

Might have a few options for full leverage there, but if not, likely sitting at around 65% LTV on anything long-term/DSCR

Last couple places were complete gut rehabs and I was able to get them right and get them to work out.

I am lost on which avenue to take from the options of house hacking, buy and hold (short-term rental), buy and hold (mid-term rental), buy and hold (long-term rental), BRRRR, flipping, etc.

3. lastly since I am virtual instead of going myself to the property can I hire a house inspector and how much would it be?

While slightly more “boring”, with the amount of money you have to work with you could probably finance 4-6 $200,000 rentals and generate monthly income that could go a long way towards replacing / supplementing  a descent portion of your W2 income. 

We'd get a CONH and all of the tenants are long term tenants. 

With roofing there is no way to tell how long it will last but you can tell if it's worn out and needs replacement.
