Sell this one and keep the cash on hand (after taxes (Ouch!))

Appreciate your and everyone elses advice, very helpful! 

this is old  tried and true method of simply having you pay them to get credit cards .. there is no need to pay for this service.. unless you want to of course.. there is no magic bullet ut there that is going to give you credit and financing unless you actually qualify for it.But zero interest credit cards are used by some to do rehab and then pay them off issue is though your fico score drops like a rock the second you take on all these CC.Also starting out there is zero chance of getting any kind of business line of Credit that is unsecured.

@Michelle SharkoAnswering questions in step by step fashion:- Is it a good thing to do or not is a personal finance decision and it depends on the person asking it, their risk tolerance which in part has to do with how this HELOC or line of credit works and how your personality fares relative to taking on new debt (a person more adverse to debt might have sufficient savings and temperament to pay down/back the debt versus a financially liberal person might get in over their skii's as).

A couple questions for the group.How challenging is it to mix STR with MTR in this way?

I wish I would have done this earlier.

Next in this environment you may be challenged to get $10k rent on $1.3m property.  

We've seen our area MLS which covers about 20 counties come down to an average sold to list price ratio of 95.1% and Knox county specifically has come to 96.4 % which is lower by about 2% from this time last year and down from our peak this year of 98.5%. but it's about in line from winter 2022 into spring 2023 which was a time when rates were rapidly rising.

Refinancing to agency may make this a great dealGood LuckGino
