We have no idea what clauses may be in your contract, force majure decisions/applicability in your local courts, etc. 

Congratulations, big things are in store for you.

That being said, you may still need to disclose the properties on your loan application if held in your personal name. 

One thing you need to demand is proof of application for mortgage.

That means getting a blanket loan on 3 properties still counts as 3, not 1.  3- Neglecting to report a loan on your credit application just because it does not show on your credit report is a fraud, it's a federal offense. 

I just listed 2 months ago two units, one in east Austin and one in Round Rock and inside of 3 days I had over 50 applicants for each property.  

Would it make sense to add her to the mortgage application?

I also wanted to add 2 storage sheds so that each unit has a shed they can store extra things inMy thoughts were that if we are adding features to the units/upgrades, does that mean we can charge higher rent (I was thinking $1350-$1500). 

Took extra attention when writing my lease agreement and reviewing applications to find renters that behave like homeowners (require them to mow their own lawn to avoid lawn care expenses, all utilities except for sewer/trash are tenant responsibility) which has paid dividends in reducing headaches and keeping time spent on management to a minimum.

@Brian Sherman - Stessa is a website/application that I have found super helpful for this.
