Since purchase, in addition to the basic repairs, I've had 2 evictions, one of whom trashed the unit, for around $22,000 in additional repairs.

Property Condition: Consider any repairs or updates needed for either scenario.

I'm looking to exit of the Midwest - I've gotten different feedback on appreciation in Indiana but so far I don't think it will outpace the property tax increases, 17% (on nice suburban home) and 16% (Class C) recently and repairs on Class C.

Have to make some repairs.

Other forgotten expenses are vacancy, repairs, and HOA special assessments. 

Can i require the tenant schedule a time with repair person for W/D.

Another out-of-town real estate enthusiast, using local comparables, estimated an After Repair Value (ARV) of $40,000 with high confidence.

@Micah Loewen there is a chance the property would appraise for the value that you want, but that it would be appraised as 'subject to repairs' as opposed to 'as-is'.
