How do I best figure out what is feasible in terms of clearance and its impact on the ADU construction?

.- Stay informed: Keep a close eye on market trends, interest rates, and local economic factors that could impact your investmentsI also lend on fix and flip projects so let me know if you're looking to get an additional quote for your next flip! 

Unless the seller/lender is added to title as a joint tenant, which would be downright stupid, the only other way they are “getting the property back” after the death of the buyer/borrower would be to foreclose and be the high bidder at the auction.

My question is, typically do banks lend on primary/investment properties with such a high price? 

Look for areas with high need for rentals, growing numbers of people, and rising business activity.

I knew this property would be in high demand.

He will finance building the house. this can be done however you want -  my recommendation where I see things go wrong is everyone is high and drinking the kool aid when they go into these deals thinking they are going to be making all this money.

Any suggestions are highly appreciated. :)TS

But if you buy a property low enough and value comes in high after the repairs, you could take out most of your money that you put down when you  refinance. 

I’m currently flipping an older brick single family home in central PA - 2700 sq ft, 4 BR 2.5 BA with ARV around $290,000 which is fairly high in my area.
