Exterior paint on a rental?

[Erik Kubec]

Hey folks, we have a property with some old, cheap vinyl siding with an inch maybe of insulation.  the small house exterior  is ugly, but serviceable.  the inside is new and clean.  the neighborhood has houses in worse and better shape externally than this one.  Here are my options as I see it.

1.  do nothing
2. Power wash vinyl
3. 2+ paint trim
4. 3 + paint vinyl with vinyl paint
5. Rip vinyl siding off, add rigid foam board + new vinyl
6. Rip vinyl siding off, add foam board and Hardie plank

I would be doing the work myself.  house is single story 800 sq ft.

How much value is there in improving the curb / online viewing appeal?

What would you do?  Its rented now, almost paid off.  The idea of doing it well appeals to me.  Tenants aren't likely to trash the siding, so the increase in curb appeal should last for years.
