On one side it's good because you don't have any vacancies but it can be bad because many times rents are under the market and there might be needed updates and repairs that are hard to do with tenants in the property. 

Could be a cool asset if marketed and managed correctly. 

Qualified mortgages (VA, FHA, conventional etc.) get underwritten to Fannie/Freddie/Ginnie standards and get sold on the secondary market as securities.  

I have considered this, but due to Denver being such an expensive market to get started in my current plan is to keep buying using personal loans to secure the property for less money down.

My company has discovered a niche and under valued market in Cape Breton, Nova Scotia.

The property features two 1,400 sq ft suites on the main level (one currently leased) and over 3,000 sq ft on the upper level, with 750 sq ft already occupied, 3 small office spaces (+/- 250 sq ft each), and a basement tenant with 1,400 sq ft of storage space.The building generates $6,000 in monthly gross income from its five tenants, but with full occupancy and market-rate rents, it has the potential to bring in $10,000+ per month.Given its historical significance, stunning architectural details, and location, I’m curious about your opinion: Would this property be more marketable for sale with or without the current tenants?
