Now purchasing a home with cash is always good b/c obviously cash is king but also I think the part you might've missed is that, the money your utilizing on these home's won't actually be yours, but the banks or whatever institution you used to fix the home or make its value worth more.

Personally, and what I would do for my clients, I would connect with a local community banker to discuss the property and see if their bank would entertain this type of financing (not all banks like doing this type of deal).

In this manual (which I assume could be modified to provide to tenants) I include all the financing information (which you would not include for tenants) bank accounts, mortgage accounts, payment information, and mortgage payoff), a list of the contractors, what each contractor does, a list of upcoming planned or necessary repairs, and a copy of all leases associated with the property.

And equally for the buyer, if you want to renovate and refinance or cash out, wouldn't you have to pay off the entire mortgage at that point and the bank would know it was always the buyer paying off and not the seller?

And as my core commercial banks understood that I doing everything i could to protect them.

Are there investors here in Texas that have utilized and would recommend banks they hold series LLC accounts with? 

@Daniel Medellin Regarding your question, it would depend on the lender or bank you're working with if you want to go that route in the future. 

Hard money lenders are much more like banks and come with many restrictions, requirements, due diligence, fees, etc.

it also means their interest rates change with the Bank of Canada rate. 

No lending institution or bank would be permitted to operate with those ratios.
