Certain cap items is fixed or pretty close to fixed whether you are buying a $60K house vs. a $500K house in the same market. 

With that being said, in a worst case scenario, you can always hire a property management company to handle the day to day items if it comes to that. 

There’s normally action items that can be implemented into your management process that are more effective. 

If this is a big-ticket item, you might consider legal action against Airbnb.  

Compliance items such as adding smoke detectors, hand rails, fire resistant garage entry-door and new stairs outside.

I would only recommend purchasing items that fall into that vision. 

You make the payments to the lender.Oh, and just in case, there are more items to know about when considering a "sub to" transaction but this is just a comment on the payment aspect. 

What is the speed of the internet, is it hot water (international property holders), is it AC.These basic clear descriptive items are great because if the price is fair and it clearly states the benefits.

I would simply hire a good civil that has done development in that jurisdiction and pay for a feasibility study and let them run through all the check items.. but thats really just the start.. also for context .. these projects require 350 to 750k in CASH up front to get to approved plat status ..

But, on the other hand, if your life is very busy with your w2 job or you have a family to take care of, then maybe having a property management company will do you well and just worrying about larger items.
