Like Gary, I think that your bank is probably looking for a business plan. Progress reports as often also required and many such loans supply the funding in increments as the project progresses but they want verifiable progress reports for each new disbursal of funds. They will also want some sort of security so if you have clear title to the land that will help to get the needed loan. You will also need data to show the lenders what the anticipated costs are for each step of development of your RV park, assuming that you intend to develop the park all at one time. It would probably be easier for you to do with a phased in process, developing just a few sites at a time in such a way that you can begin to generate income with the first sites, then move to the next group of sites and so on. A great deal of the cost to develop a park depends on the level of park that you want. There is a new RV park here in a Dallas suburb that has 190 sites, an activity center, laundromat, pool, paved streets and sites, and assorted other amenities. Developing 200 RV sites could cost anywhere from $2 million to $5 million depending on the location, land cost, necessary infrastructure development, and amenities included, with the average cost per site ranging from $10,000 to $25,000.
