Now were back to a mare normal world where a person has to have that skill of forecasting, analysis, ability to "read the tea leaves" for where it's all going and if todays acquisition makes sense. 

Just focusing on the passive income you want to achieve will leave you chasing cash flow which will have you buying properties in worse areas with harder tenancies that seem to cash flow better, but will have large cap ex.Any time someone asks a question about where to invest and it can be anywhere, they aren't ready to invest and are opening themselves up to every pitch in the world on an area.

Ethical ConsiderationsYour concern about ethics is valid and shows you’re approaching this with integrity.

STR is another concern, many towns have laws against it but most towns do not enforce these laws, just make sure you are aware of them becuase they can be enforced. 

The truth is, they will keep playing games and milk you for every penny they can, then they will leave the house a mess and cost more with cleaning, repairs, and vacancy.

Beyond immediate safety concerns, the long-term financial implications, including taxes, are a pressing issue for those impacted by the disaster.

Just keep in mind that using that emergency fund to buy your next property and having tapped a HELOC already may leave you in a bad spot if you run into a similar problem again.Also, I’m not 100% sure, but I have heard that personal loans don’t your credit more so than other types of debt so be sure you look into that if you go the personal loans route and then planned to finance your next purchase soon after.

My concern is more in the legalese of the deal.

The best deal I can find today is one that you buy cash, invest a rehab and when you pull out 75% of your ARV you leave maybe a small amount of money in the deal and you break even (BEFORE DISCOUNTING FOR VACANCY, REPAIRS, etc) Yes that means you leave like 10-25k in the deal and your payment becomes $3000/m and your rent is $3000 a month or slightly less.This is for my local market and for Class B or higher RE. 

This is where I started as well, and then about 5 years later I was able to leave my W2.
