An appraiser would calculate their value based on what they call the "income method".Rents historically have also increased at roughly the rate of inflation.

Willing to explore any methods.

As @Brandon Turner mentioned the podcasts are amazing, and it will also give you a flavor to the many different methods you can invest in, for example this week @Ankit Duggal had an INCREDIBLE podcast on RE tax lien investing - was eye opening (at least it was for me).

I suspect that this may be a scenario that he is more likely to consider after a duration of me pushing the house enough to get a decent amount of interest and he realizes that he's not going to get what he's asking on it.My question has to do with the method by which I would endeavor to sell this house for him.

I personally would not use any method like that as a final determination of value but as a cursury value it can be useful.

I switched to this method a few years ago after spending so much time on tenant screening upfront only to have the people not show.  

There are also tons of rules to setting up the property business style.As for the method.

Or suggest a method to help me find one - and please don't say to look on a review site, which all seem to be scams, or to ask people I know who they use - because most of the people I know either do their own taxes or go to a place like H&R Block.And, as a final note, I am curious - how much does it typically cost to have a CPA do your taxes (either annually or quarterly if you are in the situation of having to file quarterly?)

I posted a couple days ago if it was possible to use different financial methods to obtain a traditional commercial loan but is it possible for someone to start off in commercial real estate with little to no money ?

If that changes 10 years from now I'll have to adapt - with lots of other people.
