If I buy a house for $100k and arv is $200k is it a good deal?

How does the condition of the house and its features relate to the area?

I'm new here and excited to dive into the world of house hacking.

I have an MTR-house hack in Kaimuki-Kahala area.

Hi - I have a single family house owned mostly by an Inherited SDIRA & a small percentage by myself as an in-kind distribution. 

One guy I saw turned 5 bedroom house to his room and took the 4 others and made it 8bedrooms and something like $50/night. 

Once the project is complete, you determine market rate and buy out their share.Let's say it cost $60,000 to build the house and it is appraised for $120,000 after you are done (not including the land, which you already own).

Quote from @Heather Kiddoo: I'm happy to jump on a zoom and talk about what TC's do in the creative real estate transaction if either of you are interested @Mike Hern @Chris Seveney Thanks for the offer, but we have an in house team and use attorneys / escrow companies for all of our real estate transactions. 

I found a house that comes out to an IRR of 11-12% when I run the numbers.
