I'd give this to her after the 20th but before the last day of the month, she could pay up between so hedge your bet, hopefully she understands your position.Because the garage is a 2 car,,it's  probably not dividable, I'd make it only available to one unit and include the up charge in the lease rent, no issue then when one party is over stepping boundaries inside garage.

As @Rich Baer says local lenders will be your best bet.

Hey Amir, I've been surfing the web for places around Cleveland- specifically Parma.How did your trip go?

It acts more like an application than a web page. 

Hi Patty, I emailed you my contact info to the email on your web site.

I bet credit card issuers have that process down...I would in thier shoes.

I am probably considered conservative to want to have a certain amount in the bank rather than just betting that the new house would not have repairs.

After expenses, I bet you're making less on this home than you would if you just rented it out to a family for a set price.I just did a quick Zillow search of 5bedroom houses near the university and almost every one rented for over $2,000 a month.

If you want to do it there's no reason you can't put in a clause saying if it exceeds that amount all bet are off.

After that, your best bet is to study airbnb and vrbo.
