Frank Rolfe says: MHP value = Lot rent per month x # of units x 60 or 70Laura Cochran says:  MHP value = (Lot rent x 12 x # units)/19% or higherBasic real estate common sense says: MHP value = NOI x market multiple (or divided by market Cap Rate... pick your fancy)The problem with using the NOI is that you can never trust a seller's numbers. 

I have looked into adding my name to the deed as joint tenants, or tenants in common but my biggest concern is that if anything were to go wrong (e.g. while renting it out), my dad’s name would still be on the deed and therefore still partially liable (I would like to assume full legal liability).

Built in 1980's, some deferred maintenance, have not done inspection, I expect surprises--but since it is inhabitable I do not plan to make any value add changes until the bridge loan has been paid off. 

The Arrangement*Jack* and I met a few weeks ago, have a lot in common, and want to flip a house and share the profits 50/50. 

We live in CA which is a common law state if it helps.

There is a somewhat trend for people to live in smaller lower maintenance homes, this is not necessarily against MFH. 

I picked "UpTown Detailing" instead of anything with either my name or the common wash/soap/shine/etc references.

Utilities are generally public and you can call them to get averages, taxes are public as well and can be pulled either from a assessor website or at their office, insurance companies can give you cash value and replacement value quotes by giving them an address, general rule for running calculations for vacancy is 5-10% of gross income, I have seen maintenance expenses all over the map (anywhere from $300-750 or a % of the rent - those vary depending on the number of doors in the deal as well as how much deferred maintenance has to be dealt with or how much rehab you are going to do to negate the deferred maintenance), contracted services, call a few landscapers and get quotes and use those for your analysis. 

If the rest of your buildings are running smoothly, I'd say the only common denominator is that TBT PM.Another idea is to send a "secret shopper" to go through the tenant onboarding process on these vacant units.Yet another is to see if you can reach out to your remaining tenants (under the guise of a customer satisfaction survey, for example) to see if they can shed some light on it.
