As well i am seeing it on the ground, for standard rentals.

Standard preferred risk carriers typically won’t insure short- or mid-term rental properties, but we do have a couple of solid markets that can cover you properly. 

Quote from @Gregory Wilson: I'm not a fan of jargon in responses to new persons who may be intimidated by such usages:"Lender purchase overlays" - Additional restrictions beyond standard lending requirements that some lenders impose"FULL CLTV payment" - Combined Loan-to-Value ratio issues.

With tech-enabled platforms, turnaround time has been noticeably shorter.Consistency: Reports feel more standardized, which helps when multiple lenders are reviewing.Transparency: Having clearer timelines and updates reduces a lot of lender anxiety. real, or is it mostly marketing hype?

Is it standard to put eyes on a home 100% of the time before you submit the offer? 

The reason I saw the last part is some states/areas do not require wholesalers to have their license as a wholesaler which reduces the professional standard needing to meet.

If you haven't filled one out before have them show you what's needed.Then negotiate the deal with the seller, fill out the contract with the details you just verbally negotiated and have them sign it, then have the lawyer/title company handle the closing.If you're doing a lease option or agreement for sale you'll need those specific contracts not the standard one.

HVAC: Is the ROI high enough to justify installing high-efficiency furnaces/boilers over standard units in a mid-range flip?

Cost: What is a realistic cost-per-unit for getting a distressed C-class property up to the City's current point-of-sale/Certificate of Occupancy standards?

Is it the difficulty of finding reliable contractors, the cost of rehabs, or maybe dealing with local lending standards for the refinance step?
