(still a good option)Bandit signs can also be pretty cost effective but just be ready to hustle and put these signs all over town (not a big fan of this approach, but I know many wholesalers get massive deals from these) In the beginning I had more hustle than money, so I hustled more using cheaper marketing methods such as these.

I'm more conservative in my approach but I'd say you at least need to have enough for the down payment, closing costs, etc. plus a healthy reserve so that you can cover a vacancy of a few months as well as the ability to cover the costs of any unexpected maintenance and/or capital expenditures.

Most residential sales utilize the Comparative Market Analysis approach- find lessons on that, I'm sure there are some right here on BP too....feel free to reach out for specific inquiries, I'm an open book

Most likely I will be by myself even though other agents have approached me if they can go under me later.

I understand every situation can be different and require different or creative financing approaches.

If he/she thinks they can help, I would be happy to reach out myself.The basis of my questions is rooted in which approach would ultimately be more cost effective.

I would also always encourage having ethics when approaching a deal.

Is an FHA my best way to approach this deal?

@Jonathan Klemm I will be honest, I know little about the finance approach.
