You are correct; I made an assumption that we wouldn't be able to sell through a realtor based on the factors against us.

Your main concern should be whether these bedrooms and bathrooms on the lower level are legal and have the proper egress require for fire code and livability.

So trust is a huge factor here.

Some assets can be valued significantly lower than their actual worth because of illiquidity and other factors.

We do not factor in capital gains tax in our final net profit projection Hope that helps!  

UPS box is more expensive, but can do more things such as used as a business entity's main address on record.

@Gustavo Delgado Tax Saving is one of the factors people consider while investing in RE.

The problem is that they are not knowledgable enough to understand that the analysis is inaccurate, but start making investment decisions based on the analysis anyway.That is one of the main problems I wanted to solve with DealCheck by providing a tool that takes most of the guess work out of running analysis calculations and evaluating rentals/flips/wholesale deals that will satisfy 80%+ of investors out there.But going further, I think that tools like DealCheck are perfectly viable even for more experienced investors.

Bathrooms if you can zero threshold people love those and as they age out they need it anyway but that would be for main level. 

The main advice I would recommend is to begin networking.
