I poured the foundation myself using quickset cement ($30 plus my time).

These really old houses don't have cement between the bricks, it's lime and sand mortar, so it's not very secure when you dig under it. 

It may be a cliche, but I do know of a few anecdotal instances of doctors and dentists who invest through a partnership. 

The scope of repairs include: complete renovation of master bathroom, kitchen, and guest bathroom.I spent about $1,700 on materials for the master bathroom (vanity, lighting, tile, grout, 2 medicine cabinets, cement, drywall, etc.).

I have heard of people pouring cement down drains, and they frequently take appliances, and often other things you would think should be in the house.  

I have done framing, trim, repaired cement, power washed homes, yard work, landscaping.

The buyer is a dentist with $200,000 to put down on a house and had a FICO score of over 800.

I’m a 25 y/o Dentist in Canada, thinking of specialising in the US (2 year program) and live in the US afterwards.Any fellow Canadians here that can give me a general idea with tax/setting up corp and all for US RE journey?
