You're going to want to follow the following general rule of thumb:- 0.5 mile radius- same zip code- Sold in last 3 months- Same unit count- Same bed/bath count- Same square footage(this is not fully exhaustive but they're the big ticket items)If the appraiser selects comps that are closer matches to the above than the comps you want to use, you're going to have a tough chance arguing for the usage of your comps over theirs. 

I am a subscriber to the Playlist Beta memberships and would like to access the bonus items. 

What's somewhat interesting to me is that there is not a line item for survey.

(This should be cheaper because no personal items are insured.) and then insist the tenant’s get renter’s insurance.

The three items above along with setbacks, landscaping and storm ponds if required dictate your footprint.Find out what the DOT's variance process is and follow that. 

At that point, start stabilizing the properties, proactively spend some cash on big ticket items (roof, furnace etc. that you know are coming due) or upgrades, then start paying them off.

When I start a design project a survey is one of the first items I need (after establishing a program and basic project feasibility). 

Item 1 could be done by the owner and owner selected subs, items 2&3 are typically handled by the builder/GC.

If I were you I would be looking at this as an opportunity to really negotiate price and other items that you want to make happen (credit back at closing, fully furnished and more). 

When I've sold items on Facebook marketplace before or given things away using my Buy Nothing group, I've always checked the age of someone's profile and any public info on their profile along with evaluating the conversation to see if they pass a "vibe check".
