It is amazing how many times I have seen the cash flow represented as rent - PITI and to compound the issue they did not realize the ADU would increase their property tax.   

My estimation was with leverage I could do about 7 homes a year and each year after it would increase. 

Its a nice little cheat/loophole on the mortgage side that can help afford a larger home pice and increase your chances of getting a home or other loans.If you have any questions feel free to reach out I am always happy to help and go over the basics.

If you can or do trust your PM company then speed can increase and costs decrease over time. 

I suspect that is unlikely with the increased need for housing.  

Would we see increased cross-border transactions and a surge in property investment opportunities?

Recognize there are challenges doing BRRRRs since the rate increases that have occurred in the last couple years

Higher assets or cash in the bank increases what is called you compensating factors which banks/lenders use to qualify.

That will most probably be offset by an increase in new mortgage costs and increased rates. 

The first couple is a no-brainer.The second group has too many people, increasing wear-and-tear on the home.
