This is a relatively cheap but very effective way to seal penetrations through foundation walls that we use in all of our projects.

(I'm only willing to do that because we are here and relatively skilled and are willing to do work ourselves). 

If an individual earned a decent base income from a FT job (relative to the area), then doing owner occupant maybe 3 times in a row, for example, should not a problem...

I relate and I feel the same way.

My name is Richard, I'm 31 years of age, I work for the government, a big-time fitness enthusiast and just recently inherited a small chunk of money after my mothers passing.

Both expensive to fix, but properly venting is relatively easy. all heat rises, so the majority of the heat in your home will end up in the attic. if there is nowhere for it to go, the long term damage can be nasty.

Also, if anyone has any thoughts about going into a relatively hot market like West Palm Beach with this house-hacking plan, I'd love to hear from you too.

Unless you manage the property for free for your family/relatives/friends.

On 11-6-2017 when the property had been assigned to myself I contacted tenants to schedule annual inspection, I was told it would need to be done at a later date due to their schedules.I received call from painting contractor who was reviewed cabinet photos, Silverstar would not bid on sanding & staining cabinets since the dye lot would not match, they are showing normal signs of aging.

Can't think of any major issues related specifically to multi units.
