I know that’s not the only reason to invest in real estate but simply put it’s what I’m mainly looking at and In the markets I am currently looking at, it look like regardless of str, mtr, and ltr, I’ll be cash flowing around 150-300 a month.

If the eviction goes to court, then there is a record of that eviction on their file and it will make it harder for them to find another place to live (assuming the landlord does a background check).Not renewing the lease happens when either party decides they simply don't want to renew the lease. 

I think what you're really asking is how to identify good value areas where rents may be trending upward but the prices still remain relatively lower.An important metric is tenant household income to rent ratio.

Looks like you've identified all the good options.

For your existing vacancies - there are no proactive measures - simply active or passive measures you can take.

Create a simple spreadsheet or written list to compare the features of each and identify the ones that align with your requirements.

Through this journey, I’ve built strong relationships and developed valuable expertise in:Researching micromarkets and identifying comparables, potencial Accurately estimating construction or remodeling costs.Securing fast and reliable financing through partnerships with two top hard money lenders in Texas, offering competitive rates.I’m on this platform to connect with capital partners who are seeking an annual ROI of 12%-15%.

You may not be able to simply Google them.Here's my overall reaction to your post.  

They were referrals and the business started to grow simply because I had a competent team that was responsive and looked out for the owners' best interests.

Further, deals that are “great deals” aren’t advertised as such; they are identified through analysis using information not readily known and negotiated on a one to one basis.
