Try a "cool" front door color to make your front entry more attractive/different, and add some inexpensive landscape improvements, like mulch, to boost the curb appeal.Godspeed!

Once our house is complete, we will then get a mortgage + improvements, which will essentially be a regular mortgage but allow us extra cash to do interior renovations, landscaping, and build a garage.

We are not slum lords, we are people looking to make a little money and change the landscape. 

No exterior, roof or landscape maintenance, either.  

They get to meet everyone we work with from our contractors to our insurance company, our pool man to our landscapers.

She has done a good job taking care of the house, has fixed things on her own, landscaped, painted, installed new ceiling fans, etc. and not a tenant who will call me "for a plugged toilet" as she can fix that on her own.

Option B. stay month to month but rent will go to 5% above option A.Not sure if that's Kosher but seems fair to me :)As far as average market value, really I went through zillow and craigslist to see what other 3/2 houses in my area (ones that are fairly turn key as that is the scenario with mine, granite counters, stainless steel appliances, landscaped yard, etc) go for and they all go for way over what I'm charging now; but that was me eye balling it.

You may want to look into renting to a landscaper , or small contractor who needs outside secure storage

Change the name, add some landscaping, and start cleaning the place up. 

Being as you are in Indiana- I highly recommend checking out Alpine Property Management in Indianapolis.
