The current rents are really low because the tenants are responsible for doing any and all repairs on their buildings (which in my opinion contributes to the poor condition of the buildings). 

Some even offer preferred interest rates as low as 5.75% at no cost to you. 

Because, it's way too low. 

Thankfully we are commercial bank clients so our rates are as low as you can get in the market place for anyone who is not Lennar or DR horton or those types.

A B class rental here is probably different than a B class rental in your area as is the profile of the tenant that occupies it.

With a purchase price of $250k, your rent is WAY too low!

I really want everything in my profile!

Also, what are some other low cost amenities that I can add to my STR that will yield a higher ROI?

I was thinking of starting a rent increase for my 1 bedroom tenant voucher due it being low and well under fair market value(Based on  hud and zip code) but my tenant is in the process of having a caretaker for her disability and getting approved for a two bedroom voucher.

Then the prices lower towards the date and you end up booking at a low price or worse just being vacant.I think manually pricing your STR'S is a much better approach.So many people are looking for the next cool software app to buy a subscription to.
