None wanted to give me at least an estimate without architectural drawings, which I guess is understandable.

Quote from @Mike Sfera: for a duplex, is the BP rent estimate for per unit of combined?

Based on the quality of this particular home, my rent estimate may be low.Note: you have to consider other factors.

That is roughly 9% rent price appreciation over the original rent estimates. 

The property alone is worth a million but is generating an estimated $250k/ yr with the ability to add 3 units on site and acquire an additional 13 acres.

So what I'm asking is if there's a better way to estimate CapEx on a property during preliminary analysis, i.e., without having to go to the state where it's located and asking around, i say this because there has to be a good way to estimate these things before going deep into the dealAny insights on this guys?

Using Rentometer or BP rent estimator to get an idea of the LTR rent makes a lot of sense.

But then he said they had to have a contractor’s estimate on the Indiana house and the money would be doled out as things were completed, so could not be used in Spokane.

My partner called the owner who had give the original estimate, said no way are we paying until the job is done. 

I put property taxes 6k/year on each(Even though that's way higher then what it actually is, but the county tax estimate says its around that much for each) and for insurance, I just put 1,100/year on each.If there's more info needed let me know.
