I am a property owner in central Texas of a multi-family home.

I am doing owner builder so hiring subs for each job.

Real estate loans to owner occupied properties where the business of the owner is closed down - or SHOULD be, and the owner needs some time to sell the property.  

It was the worst house in the best location. 5 acres just above a lake outside of a desired town.

We have a mixed use apartment/commercial property for sale where the owner would entertain seller financing.

The previous owner who was planning to make a pet hospital had some of the drawings and plan done on this old building.The previous owner also had no plans for addition or extension of the existing building since it requires zoning of a plot which is more time consuming process based on the feedback I received from county and a couple of civil engineering firms that I reached out to.I was provided the following list for civil engineering work.Pre-construction phase1.

Tons of rules here which make a condo association "warrantable" vs "non-warrantable" but just one on the list: one owner owning the majority of the units alone will typically make them non-warrantable.

Also, the term "house hacking" is generally used for your owner occupied home (renting out rooms in your primary home) and that income cannot be used to help you qualify (it is considered boarder income).
