@Sean GammonsConsider adding a partner for the second deal to share the down payment and mortgage responsibility, keeping DTI manageable.

I'll definitely reach out if I have any questions.Your offer to share tips and tricks on the finance side sounds incredibly valuable.

Definitely connect with more people on this that’s willing to share their experience.

To maximize your chances of success, recommend sharing that and the percent increase in taxes & ins with tenant and asking them what they think a fair increase is.- If they say $0-$50, you'll have to get rid of them at end of current lease.- If they are more reasonable you may want to accept if for now, but let them know you'd be doing regular increases to get the rent more inline with market rent.Too many newbies here will tell you to get market rent or get rid of the tenant.

Say my neighbor wants to buy a 1 millimeter strip of land along our shared property line for 450k. 

@Michael Plaks interesting feedback, thanks for sharing. 

It's always inspiring to see fellow real estate professionals who are passionate about learning and sharing insights.Phoenix is a vibrant market with plenty of opportunities.

If you want to reach out by DM, I’d be happy to share some insight.

Also, I have coached a few agents who wanted to get more heavily into investing and I am happy to share what we found worked easily for them. 

Chances are this is NO deal property as the X will want their fair share and a fair market appraisal will need to be done and the equity split equally.
