Under those 4 windows you need some beautiful flowers right across under every window purple, red or something that stops just below the windows, that alone is your cheapest curb appeal. 

You need to look at rental rates in your area, and if you have to weasel clause in your lease like the tenants must mow the lawn, water the plants/flowers, trim the plants, that could scare away tenants.

Secondly, if you've purchased a house that needs a little help, you would be shocked at what paint, new fixtures and a few flowers can do for value.

Surprise her with flowers that day.
