IF that is the case full stop - yes you are paying for something called insurance but if you have a claim the company has the right to pretty much deny coverage for having the wrong type of policy.Landlord policies are higher cost but for a reason - there is a different and increased level of risk when the house is not owner occupied.Talk with your agent and get all the details sorted out. 

Quote from @Don Miller: The following is not to express any level of happiness or unhappiness with the build:Received change orders totaling $14,970 for 18 additional loads of fill dirt over allotted amount in contract (fill dirt arrived in December 2022), 7 loads of septic sand over allotted amount, and rock excavation at the septic site. make sure to ask for the tickets. if they are putting 6 yards of soil in a single axle truck you are getting ripped off.

I think you’re with the wrong turnkey company.  

Others have little/no experience and will give you bad advice that takes you down the wrong path.I recommend you focus on educating yourself while saving more money. 

Take all your analysis that you did for the deal to court so you can explain why they got the value wrong. 

@MIchael McCUe Wrong ,.....

Don't get me wrong the market goes up more over time then down but if you happened to take out the loan when the market was at a high point this would actually be a win for you.  

Lots of experience, has some reserves, good market and flipper has a healthy income to recover if things go wrong (probably Not a problem in this situation)4.

And it would only be an estimate , not a firm price , things go wrong all the time , so giving an exact number would be difficult . 

Not only is there nothing wrong with taking this approach, but I actually think this is the best way to start and the way that 99% of new investors should start their investing journey.
