I don't have much money for the next property, but am ready to add to my profile.

Quote from @Carlyn Chism:I agree with Chris on a lender that might be a scam or make you may so much money interest because of the low credit score that you make $1.00 on the flip or no money.  

I have been in the search of lenders with low or no minimums for purchase/ refi. 

Great to meet you.We source from four primary suppliers: Lowe's, Home Depot, Floor & Decor, and Amazon.

We have 2 potential renters for our property. Has anyone had a renter on an assisted housing program? What are your thoughts on these types of tenants? Good or if there any red flags? Appreciate your thoughts?

I would recommend you use the profile page BP.  

Also, what are some other low cost amenities that I can add to my STR that will yield a higher ROI?

Additionally, it feels the most appropriate approach for both profiles I described above and allows me to focus on learning one strategy.

One thought was to replace to large commercial tenant with a company that had a similar profile.

I actually took a look at your profile and made some tweaks to mine.
