I should probably make a similar post asking for advice on how to better utilize the space.

That means half of your mortgage interest and half of any shared utilities.

Utilities in this area (-electric, water, sewer) are about $100 monthly if occupied. 

I utilized a home line of credit on my first primary residence to purchase my following two real estate deals.

We will be moving out at some point and renting the entire property; each likely moving in our own directions with future investments, but both wanting to utilize the HELOC for these investments (e.g. down payment, renovation, etc).

For the other numbers like landscaping and utilities, you should use a general number.  

Don’t forget bringing in 4-6 sets of utilities, driveways, etc. 

Wish I utilized this more early on in my wholesaling ventures. 

Or maybe some utilities.

I would pay close attention to the law though as it states that if you WILLFULLY withhold that information you cannot utilize the deposit.
