Putting in a ramp, adding grab bars in bathroom, raising the sink height, etc.  

I recently added a half bathroom to existing footage in a unit that is valued over $1k/ft that the comps showed the half bathroom added ~$50k of value.- not sure of your home market but i assume you are choosing ohio for its lower cost.  

That ship has sailed and it was never at the discount you're suggesting. 

(So unless they sell for much more than they paid they will only get a small percent of their down back, especially after selling costs,) but you did say they were getting a discount.

No kidding we just get them to discount the price by our commish..

I did talk to an agent who bought SFH in San Jose at a discount and is renting out by the room. 

I recently added a half bathroom out of existing space in a very high cost market.  

Especially if you're doing enough volume to get good discounts on products.

I guarantee virtually no one is meeting that rule in SD because they're all on here looking to buy in Cleveland or Detroit because in that market price to rent ratios are so askew that buying at a 50% discount probably doesn't get you the 1% rule. 

- The market is in a little bit of a lull right now (buyers market), its a great time to buy, but slower time to sell (my primary business is flipping houses) I can supplement my flipping business by providing project management services/consulting, helping investors find discounted properties, etc. etc.
