With the profit from the first deal I would pay for the initial investment technically.  

Criminal background will weed out some bad actors as well.  

Its no surprise that also took them a week to go and turn it off.I had 2 perspective tenants waiting for over a month with their national background check only to find out there were alternatives we could use to get a report in minutes but they refused to not use that company.Finally I get a tenant after 3 months on the market who is someone who was fully approved by the rent amount was 200 dollars less than market value a month so I agreed because it was just before winter when its harder to get someone in.

@Ryan Daniel  I will preface this with the fact that I have a legal background, specifically with estate planning and asset protection in relation to real estate investments.

Leasing is a specialized skill—PMs deal with this daily, making them far better equipped to handle applications, verify income, conduct background checks, and evaluate a tenant’s overall suitability.Protecting Your Investment:The cost of a bad tenant can be far greater than the cost of hiring a professional.

Zillow screening doesn't catch all backgrounds, but Forewarn does and county records do as well.

My professional background is data science / analytics, which means analyzing cash flows will probably come more naturally than building relationships, which apparently, is how one finds deals worth making.Are there meetups in these areas I should attend (digitally at first, presumably)? 

Alternatively, I have spent the last decade doing technical work in cybersecurity, and can land a job between $140k-$190k (depending on where in the US). 

. $1 is technically cash flow and if you buy a Lake Tahoe lake front house and cashflow $1 I'd take that all day.

The ADU would then be used as a long-term rental.Does this qualify as a “like-for-like” property exchange even though I’m technically not buying another property and does a 1031 apply?
