Both have the same 3-story configuration.

My first visit was not quite as dramatic as yours, but it was a disappointment because the house (duplex, actually) was configured so weirdly I had no idea who would even want to rent it, lol.That said- is your disappointment due only to the state of the house, or is it because of you were to put money into rehab, you'd have no hope of recouping it from rents?

REI Pro is already configured to do what is most important to investors.

So I'm assuming both building A and B are configured to be able to sell as separate units sch as individual meters, kitchen and bathrooms, in other words they meet your areas zoning code standards to be sold separately.

Maybe one day when I get more advanced, or if I had a local mentor that could show me how to configure the paperwork.  

In an up and down configuration, you may have an upstairs unit that gets very hot.Showings/Turnover scheduling.  

Depending on the zoning of your property, the configuration of your lot and the construction of the garage, you may not be able to get a CO from your city for the extra unit.Your best bet may be to make use of the space yourself, provided that your tenants still have proper parking.

It's possible that the configuration of the lots makes it difficult or undesirable to build what the HOA requires on those lots -- or is difficult to adhere to HOA covenants while still adhering to zoning rules. 

The key is that each tax payer purchase at least as much investment real estate as they sell.However you configure the sales (and each sale is a separate distinct exchange) does not matter as long as you take title to at least as much real estate as you sold in order to defer all tax.  

You can get the bonus round if you would ask them if they would pay X for a property with Y configuration in Z area.
