I was advised by a developer friend to just speak to a title company that frequently handles new build subdivisions.

Frequently  the attorney fees are minimal because the attorney can get a commission from the title company if they are a title agent.

You typically turn these over more frequently than other units. just be sure to factor this into your overall analysis when you do the numbers especially if you are using property management.

These are similar homes, but the small differences cause them to have different appeal to different audiences (renters vs. purchasers), which cause significant differences when one calculates the CAP rate of each.     

All the extra bathroom does it appeal to a wider audience, but, the extra bathroom also comes at a higher price (maybe only $50), so it then appeals to a smaller audience.You could talk yourself in circles on this stuff.We've never had a any problems renting 3/1s.

Do you have the time and/or team in place to facilitate quick (and frequent) turnovers?

Once the end buyer realizes the fee/commission they are paying the wholesaler, they frequently go directly to the Seller, offer more money to the Seller and save money themselves.

I think, at this point, keeping frequent and considerate communication will certainly help here. 

There are also multi-family units in some of the rougher areas of London (King Edward, Argyle etc) where you can potentially find rents in excess of 1%. 6plexes on King Edward can frequently be had in the 350-500K range and are often getting 600-800/unit in rents.

The larger your target audience the more stable your results. 10.000 addresses will yield you 10 deals for the cost of 60k.The numbers may be different, I made them up as an example, but that's the type of math that goes into it.
