The timeline depends on the product you use to do your refinance back out (after buying all cash with no liens).

Secondly a 7% rate with 1-2 points depending on LTV, FICO, DSCR, and prepayment penalty does sound fair/market standard.

It  depends on the scale of your portfolio but if you have a couple properties and they’re all straightforward, I think google drive is fine. 

For instance, a worksheet calculator that you can depend on for accurate rehab numbers, a coach or mentor that has experience wholesaling whose brain you can pick, a curious, principled solution-based mindset, willingness to find sellers that are NOT on the market, and for good measure -- steal underpants!

With that said and depending on how rural it is you may be able to put gravel down and put a fence up and have RV and Boat storage.

Also 3 brs will get anywhere from 1k- 1600 depending on where, YES they pay MORE than cash tenants.

@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).
