They are the absolute worst!!!

Several years ago when the low flow toilets came out, some just didn't work well at all.

Every flipper has found themselves at Lowe's for the fourth time in a single day, picking up yet another piece of material for a project.

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.  

Specifically, I am looking at partnering with an individual who owns securities (stock and mutual funds) having them take out a line of credit against their portfolio (SBLOC) at a low interest rate, and using that to purchase properties rather than using a mortgage.

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

It’s just more than I can afford, and I don’t want to offend you with a low offer.”

say you find a solid property in a low cost market for $200K and you buy it.between down payment, closing costs, rent ready / spruce up costs, and lease-up costs, you're probably going to need at least 50-65K in cash. 

Rates are high, usually in the high 8s or low 9s, and you may pay 2-4 points on the loan. 

Low or no down, seller financing and low or no interest with a balloon payment later is the holy grail (location, building condition, market also matter but it sounds like you have all that).
