Welcome to BiggerPockets Michael and best of luck investing!

What is the best way to increase her rent?

In my experience trying to raise capital from people within the real estate community doesn't seem to be the best method because most people in real estate are more interested in building their own businesses, rather than investing in someone elses (especially when considering how much money it takes to invest in syndications).

And make sure that all items necessary for you to get the best rate possible from your carrier (like 4 point inspections, roof attachment points, pool enclosures etc) are present or available.One nasty little factor that can't be helped is that every time you buy a property for more than than last owner paid - you will have a tax bump due to re-assessment.

I found the best solution was to set up auto pays for all the accounts and then make a google doc with all the info broken down by property for periodic reviews.

The appraisal came back low because the highest and best use is whatever is legally zoned.

Also, concerns surrounding potential valuation corrections in this market had me thinking it was probably best to pull my capital and redeploy into a more 'stable' market/LTR. 

It's best to check with your local zoning department before making plans to move forward.
