You might ask if they offer referrals for traveling professionals or families on extended stays.

Any good referrals for an insurance agent.

I get the best contractors and referrals from investors doing this day in and out and who already have a solid contractor team in place.Where do you find these big players?

I would look at the type of Urban Companies, which tend to be large firms. 

I also tend to rent more 2+ bedrooms to the military than my smaller units.

I definitely tend to skip any questions that are way too vague or of the TLDR variety. 

You should still be able to find a few lenders to do smaller rehabs like that, as long as the ARV supports it, and often times the BRRRR tends to work better that way because if it is in a good Sec 8 area with rents that support the ARV, the refi can work out well.Happy to connect and talk through details if you are interested!

I like duplexes because they tend to cash-flow better on average. 

Specifically, I’m looking for insights on cost projections, especially whether the cost per square foot tends to decrease with larger projects, and what budget I should allocate to ensure this development is profitable.Guidance from someone with experience in similar projects would be invaluable

Make sure the Flat Fee Company is NOT a referral service, that the broker is reachable and licensed ... check reviews and license numbers (licenses should be listed on the home site), they should allow at least 25 pictures, no charge for changes, and a good customer service.
