Thanks for the advice.We are getting the samples taken for proper testing.The house is built in 1962 and we are planning to renovate it which would involve removal of a couple of walls to make the layout more functional.

@Jack Taylor - if you are more of a visual person, here are some diagrams that might help you further on this quest: Asset Protection Decision Diagram - to help assess the need for asset protection, and what to implement: https://www.biggerpockets.com/files/user/CosIorg/file/asset-protection-decision-diagramAsset Protection Onion Diagram - what, when, and at what cost one should implement in terms of asset protection - https://www.biggerpockets.com/files/user/CosIorg/file/asset-protection-onion-diagram-v2What is needed for complete asset protection OR the domains that need to be intersected to find asset protection - https://www.biggerpockets.com/files/user/CosIorg/file/asset-protection-spectrum-diagramHow a fully implemented asset protection layout might look. - https://www.biggerpockets.com/files/user/CosIorg/file/asset-protection-structuresIf you want more details, from an investor perspective, PM me. 

I agree that if you lay out everything upfront I can imagine it would be less of a headache down the road as with a lot of things in life.

This is all based on my subjective experience and intuition, but the biggest questions I asked myself in deciding how wise it was to take on more debt when I already have debt were: 1).

Layout-wise, the STR with 5-6 bedrooms resulted in the best ROI. 

Obviously I have no idea of your property layout for if this would even make sense.

Re: finding appropriate properties, I think you'd want layouts with equal numbers of beds/baths (ideally), kitchens with good storage, and appropriate parking options if the area demands a car.  

SFR Purchase Date, Loan Price, Interest Rate, monthly payment, and home layout: Dec 2022, 614K, 6.25%, 4300.00 a month, 1 Bed/1 Bath/590sqft/3800 sqft lot  Current Assessed Value: 633K (Average from Trulia, Zillow, Reding, and Realtor.com) Assessed Rental Value: 2300.00 a monthOriginal plan: Take advantage of my lot space and build a 2 bed/1 bath DADU on the property to rent out at around 2500.00 a month.

Intuitively, I kinda expected term and invest the difference to come out ahead (I would have still been OK allocating part of my money to whole life premiums), especially since the cost per $1,000 rises over time in whole life and universal life.

@Katie Willcox I've noticed in my business if the application is easy, intuitive and user friendly people are much more likely to take the time to fill it out.
