I did a cash out refi on my principal residence at a much lower rate and paid it off.Now I plan on using the equity for more purchases.What? 

I probably wouldnt trust it 100% with that though unless I input all of the data that I have from my analysis in terms of ARV, rental rates, rehab rates, etc. now that I type it out, that actually would be a good idea aha. 

Rated Very Good.2.

Removing problem tenants and re-renting to new market rate and respectful tenants.

The issue here is in order to increase rents at reasonable rates to cashflow well you need to not just do cosmetic changes they require you to do extensive plumbing and electrical to be able to increase the rents. 

First, developing your awareness of the STRs around you is key to knowing how much someone is charging at any given time, the market's occupancy rate, and how much revenue your competitors are driving in.

I don't even mind paying ridiculous interest rates as I understand this is a big ask.

When financing these projects, keep in mind that some lenders may require a larger down payment or charge higher interest rates due to the increased risk.

After reviewing the standard numbers on population, jobs, income per capital, crime rate, appreciation potential, etc., I was not overly impressed but decided to move forward despite the numbers due to the amount of rent/sqft in comparison to the cost/sqft.

When considering single-family homes (SFH) or small multifamily properties, it’s important to analyze rental demand, local property values, and rental rates to ensure you’re getting strong cash flow potential.
