Adding and making better could sell or rent faster, but it won't get you more than what the market ARV and rent is set at from other similar comps in the area....and your Interior Design background will help, if you you it mostly as an understanding of cost. 

Start by asking what the numbers look like. then ask yourself, do you and your aunt see things similarly or do you have very different ideas on the property? 

Hi @Christopher J Driscoll I am doing something quite similar to your approach, my ADU permit should be approved quite soon, I am still waiting on my last LADWP clearance.

Any guidance from experienced investors, real estate professionals, or anyone who has faced a similar situation would be greatly appreciated. 

Publication 336 (cash method section) gives a clear example very similar to the situation described where constructive receipt was made because the agent of the taxpayer received payment for the taxpayer. 

I've also been in a similar situation in the past and solved it with a wrap.

Are you looking to do more and similar flips?

Stealing stuff out of an Airbnb is similar to unloading the TV, bed and mini fridge from the Marriot.

Eddie I'm in a similar position as you with the same questions. 

Hmm, so i just bought a condo in weehawken and spoke with the township and had a similar discussion.
