As for other amenities, some crowd-pleasers that won't break the bank are coffee maker + starter pack of pods, basic workout equipment (yoga mat, resistance bands), phone charging stations by the beds, and basic kitchen essentials like olive oil, salt/pepper, coffee filters, etc.

So at this point, IDK, I think maybe the Boggy-man looks under his bed to see if I'm there, lol.   

@Lindsay Davis"$150,000 can buy you a tenant-ready 3 bed, 2 bath single-family home in a B-grade neighborhood.

Get good beds, pillows, sheets and don't simp.  

In the event my landlord is interested in selling, I was wondering if I could add value in the short term by, say, converting part of the garage and/or covered porch into a bathroom and maybe a bedroom (currently 3 bed 1 bath).

The initial thought is you are probably charging too much if no one is interested, or your photos or description are bad.Four beds and only one bath probably reduces demand as well, that’s potentially a lot of people sharing one toilet.And it is winter - I’m in Buffalo, I hate listing rentals this time of year.

Whats the bed bath count, and sqft?

You can go to bed at night sleeping like a baby even though you charge 4X what others get because you know, you helped fulfill a couples LITERAL life dream.

My current tenant has removed a picture from the wall and replaced the provided bedding with their own belongings.
