The rest of the house is in great shape with some layout issues that I have a plan for.

If I could find a house in the area with the same layout I would do it again but it's tough where we live.

It's not intuitive. 

I think you first need to reverse engineer title and layout a timeline of event and record documents.This will give you a better idea what a title company will be looking at and questioning you. 

It is actually very easy to analyse the property since all condos are the same layout, we know immediately if the price is right.

Lay out your expectations and make sure your quotes for various projects are in writing.Don't go with the lowest bid just because of cost.

@Karen Moysi for clarity:Lease-to-own is where you have a lease with the tenant, and every month they pay a small amount of NROC which slowly reduces the 'sale price' of the property until they've paid enough and they hit zero, or they get a bank loan for the remaining balance of the option and pay you off completely.DISCLAIMER: there is a much more technical way to say this, but i'm trying to lay out the basics.

Do you have a really good idea how you're going to lay out the units, electrical, gas, plumbing, etc?

I am not a realtor or anything, but I cant imagine that having the master upstairs is making that big of a difference unless there is something else awkward about the layout.

., firing a contractor, making changes a materials / layout design, addressing unforeseen issues that come up (e.g., plumbing), etc.
