I suspect the purchase is at ~80% of ARV but I am not flipping it so I do not have to be that precise on expected ARV. 

Just be impeccably precise with your numbers, your dates, and have all receipts in court.

The more insight provided, the more of a baseline I can begin to formulate and then I can get a bit more precise with my exploration.

(An intelligent, helpful, and precisely-targeted social media site, but a social media site, all the same.) 2) Have you approached your Lender to ask the question of whether they'll allow this change? 

If you want to get a more precise figure, an appraisal is another option.

This is precisely why I left the over regulated socialist-minded Republic of California.

If I was seeking precise advice I would definitely want to share exact numbers. 

Fourth, you are qualifying the Tenant Buyer using Dodd-Frank rules, so you have less to worry about them defaulting.This makes me feel much better, because that is precisely the model that I want to follow.

Here's the background:-I recently purchased a duplex and am occupying one unit and renting the other-Currently, the owner (me) is footing the water bill for the building-My unit has in-unit laundry, the other does not-The water bill averages $200/monthI'm considering the following options and would really appreciate any advice on how you would handle the situation:1) Once I move out, continue to pay the water bill (expensive over the long run)2) Work in a flat fee to the rent and pay the difference myself each month (tough sell to tenants)3) Install a secondary meter and charge tenants back at the end of each month for their usage (requires more work on the part of the property manager, hassle to charge precise bill to tenants each month)4) Run a second water line, completely separate bills and make the tenants completely responsible for their own water bill (most expensive, initially)What are your thoughts, and can you think of any better options to deal with the issue? 

My other concern is: Why such PRECISE "The building is worth 82 and the total value with the land is 147" figures?
