Also, focus on 2 years of job/income stability.Class D Properties:Cashflow vs Appreciation: Typically, all cashflow with little, maybe even negative, relative rent & value appreciationVacancy Est: 20%+ should be used to cover nonpayment, evictions & damages.Tenant Pool: majority will have FICO scores under 560 (almost 30% probability of default), little to no good tradelines, lots of collections & chargeoffs, recent evictions.

That would be what I would profit on a build job, then the interest and closing costs and such would be paid by the person hiring me. 

I want to scale, but not sure how to develop my strategy.I have a $200k HELOC and excellent credit worthiness and high income from my day job.

Even tough, I am in information overload right now and working a full-time job at night.

Great job.

Avoid.The majority of the Mexican developers are honest and do a great job but people need to do a proper due diligence, including knowing who they're dealing with.

Any advise on adding washer/dryers is a plus I know routing new drains can be tricky when trying not to get to invasive on a "cosmetic" job.

Plus this is literally your agents job, an agent gets paid to help you with things like this, a co-host can be super valuable but is more focused on the post-purchase phase. 

Please let me know if these builders are up for the job and I will definitely reach out to them.Thank you!

If things are tight right now, maybe consider a side hustle or extra job until rent adjustments give you more breathing room.
