Each of the properties have an estimated profit of around $70,000.

It is not low cost.. you need 7-8 rooms per house to make it decently profitable. 

I have no problem paying a wholesale fee if there's plenty of margin for me. 

My first question would be is this profitable?

Now that's flipped, which makes profitability on a simple rental much harder. 

Hey @Mike Levene, I'd recommend considering a Margin Loan against your stock portfolio.

Margins on the market today are extremely tight.

This can be helpful if you expect your property to become profitable soon.Save It for Later: If you don’t use it this year, you can save the depreciation for future years when you have more rental income.

Generally all months other than Sep-Nov are profitable. 

Anywhere that one can buy properties for under $100k is very unlikely to have the rent increases that you will need over time to create positive cashflow, or the price appreciation that you will need to make this a profitable endeavor.
