After a certain number of calls to the same property within an annual period, the city starts charging my company per call (~$250/call).

@Gregory Fazio When using seller financing, ensure the interest rate is competitive and clarify the amortization period to avoid a large balloon payment.

For those following along at home, that language is found in Title 10, Chapter 1, Article E, section 6 (or 10-1E-6) in the municipal code.It reads: "The renting or leasing of real property for residential occupation for periods of time less than thirty (30) days is prohibited in any zoning district within the town, except as permitted in this title for hotels, motels and bed and breakfast inns."

This is my opinion only, typical sales pitch period. 

If not, waiting until the penalty period expires may be the better option. 

Might consider a longer amortization period with maybe an interest only option on the front end. 

Hey Bans,  the ARM seems like a great option for the increased cash flow in the short term and interest savings for the 5 year period.

Would work the same as a BRRR just over a longer period of time. 

If the seller is now asking to be able to complete the home inspection, without first fixing the gas leak, I again don't have any issue with that as long as its inside your inspection period and you have the credit etc in writing at this point. 

I get the the post card route is way more efficient from a time perspective (although at twice the cost), but really wondering about response rates.
