I’d do the the basics yourself if you can but beyond that typically AC units are simple to fix and not super expensive

It’s not typical for a broker to charge up front fees....some have monthly fees, some do not.

Typically I repair my own appliances, however, I believe the problem is beyond my knowledge. 

In my market, 0.7% is the typical sale.

I typically like to purchase/place my properties into an LLC, but I realize this means commercial mortgages (higher rates, higher down payments). 

There are agents selling properties (typically interpreted as a residential transaction) with the short term rental business attached (typically a commercial transaction).

I typically get out of work around 5:30 or so. 

The difference is the principal gets reduced in the note vs it doesn’t on your asset but you will find that over 15-20 years you will put a good amount of $ in a rental and with a note it probably gets refinanced out in 5-10 years which typically bumps your returns higher

Typical repairs include: touch up paint, carpet cleaning, light bulb and filter changes etc.

I typically show  the apartment until I have a signed agreement/deposit in hand.
