Calculating ROI with no money down

[Matt T.]

Hello All, 

How would you look at a deal in terms of return if you have no real out of pocket money down?

We just got our first deal under contract and the local bank we are dealing with is doing a two loan process to do the deal. Property has a 3bd. 1 br home in the front and a detached Studio apartment off the back alley. 

First loan is a construction loan, 6month, interest only. - Includes purchase price and then the repair cost (total loan not to exceed 85% of after repair value) 

Second loan is a traditional commercial loan, with a $100 refi fee.

Here is how the deal is looking: Numbers may not be concrete but hopefully you see what i'm getting at. 

Price of property: $36K

Price of repairs: $10K - $15K estimated

After repair value: $65K+ estimated (waiting on appraisal)

Realtor Fee: $1500 flat

construction loan fee: $500 + appraisal, inspection, etc. (estimated total of $900)

total loan: $53,400, 25 year term, 5% interest

Rent should be around $1000 between both units

After expenses, taxes, insurance, maintenance, repairs, etc. we are figuring around $200-$300 in cash flow.

What $ values would you use to look at ROI? I have no money down in the deal, so the ROI equation would say i have infinite returns (the bigger pockets calculator confirmed this as well).

As awesome as this sounds, i don't think it is a great way to analyze deals. Thoughts on how you would look at it?

Thanks in advance.
