Most lenders will vary how aggressive they will get based on the experience of the operator (you), but I don't know any that will lender to someone who's never done a spec build like you're contemplating.

@Steve Vaughan  when we went through the 08 to 2010 debacle and over 200 landlords handed me back their houses.. and lost ALL their money... it was an eye opener and they were all landlords all west coast based   a few on east coast.but they walked..  

They are very likely based overseas.

In the end, it would have made more sense to hire a couple handymen for a week or two than me spending 3 weeks installing flooring, base and case.

As others said out of state can be more challenging based on location but local or out of state both can be done. 

It's adjustable based on size, erring on the side of generosity.

Based on comparable listings recently sold I think closer to $650k there would be more interest.  

This is how much you need to increase your room rate to become profitable based on last year's information.

I have noticed that properties that allow pets in outdoor based communities perform great as well!

Investment also spiked in Class A Short-Term Rentals (STR) and investors started paying higher and higher prices based upon anticipated STR rental rates, that exceeded sustainability based upon Long-Term Rental rates (LTR).
