Hi @Dave Anderson,This particular area has huge variations in those costs based on a few things like CBS/wood frame construction, property age, roof age, price range, and general location.

Due to the vagaries of rental house investing, you will seldom see the exact same revenue in two consecutive years and, in fact, may experience wide variations as capital expenditures come into play. 

Screen meticulously as you always do (the process must be the same for S8 applicants as for market ones with just a few variations for income).Once you accept an applicant with a voucher, there will be paperwork to complete that the applicant has from Section 8. 

Those who are leveraged on 10+ there are a variation of options out there.

Be sure you don't already have exactly what you need before changing it.It's hard to get folks who want to live in SFH only neighborhoods to approve one-off zoning variations. 

I'll offer a slight variation on the answers to-date.   

There are tons of articles on net which list the states (with some variation) such as this for example: TexasIndianaColoradoAlabamaArizonaFloridaIllinoisPennsylvaniaOhioGeorgiaKentuckyThe common theme is that these states are most protective from law perspective and have other landlord advantages with respect to:Eviction ProcessLandlord & Tenant RightsRent ControlRegistration & LicensesTax & Insurance RatesCompetitionWhat do you say?

There is so much variation from neighborhood to neighborhood and even street to street.

By that thinking, a better algorithm could help solve for discrepancies in the variations of appraised values.

Even if you have a "good contractor," they will need to educated on the 203k guidelines, paperwork, processes, timelines, rules, payment structure, variation of the 203k, etc.
