Not sure if you are asking specifically what points are or in a hard money loan how many are charged, so I will answer both and maybe help you out a little bit.
A point on a HML (hard money loan) is 1% of your mortgage amount. These are not only in HML but can be in traditional loans as well. Generally a point is used to buy down the interest rate in a loan however with a HML it is more of a cost of getting the loan. Many companies will charge points in addition to a funding/financing fee.
The amount of points each company will charge varies from company to company. Most I have seen are 2%-4% or 2-4 points of the mortgage amount. Credit usually don't matter as much as the value of the property and the amount of time you need the money. I have seen companies that give you an initial loan with 3 points but may allow you to extend the loan term with additional points paid up front. With a HML usually your points are paid up front along with the funding fee. One nice option to a HML is paying interest only so that could help with the up front cost when your carrying cost is a little lower.
With a HML sometimes having money to do a deal is worth the cost, takes money to make money kind of deal, especially compared to having to wait on a traditional loan for 30 days or longer. Many companies will fund not only the purchase but also the repairs needed to the home. When you don't have the 20% down for a conventional loan or cash in hand, a HML can be an option.
As for limited funds, you could use that to market to find deals and wholesale or work out owner financing. If you have good credit and a home you could look for a home equity line or a cash out refi in a personal home. You could always wholesale deals to other investors until your funds build up.
