In reference to this question:
2-after reading forums on here i learned double closing is generally for large profit amounts, and needs individual funding upfront, so i am better off making assignments, should i only assign to title companies?
You are correct in stating that people use Transactional Tunding in wholesale double closes when there is a large profit amount. For deals with a markup of less than 10% or $10,000, Assigning a contract is usually the best way to go. This avoids incurring Transactional Funding costs.
However, sometimes you are not able to Assign the contract. The reasons include, but are not limited to:
1 - State or county laws and regulations do not allow an Assignment
2 - It is a Short Sale, REO, or otherwise a Non-Assignable contract
3 - The seller is not comfortable having the contract as Assignable. They may want to "know" who the buyer of their house is
Hopefully, that helps in deciding which route to take: Assignment vs. Double Closing.
