We have only been open a year and the income from the property makes our mortage and construction loan payments now, but that first year there was no income from the property. Our regular income from our jobs paid for everything the first year.
Get an approval for your loans ahead of time, and write a business proposal for your lender. No one will lend you money if you don't have a solid plan. You also need to find a lawyer to overlook your contracts and policies to make sure you are covered. Contact an insurance agency to find out what type of coverage you will need and the cost.
You can not do this alone, you will have to hire someone to step in when your gone, sick, injured, and overwhelmed. It will happen. It is a 24/7 responsiblity you have to take seriously.
Good luck on your venture, just please do your homework before starting anything.
