@Nephtalie Pierre Sounds like you have 3 major options to get access to the equity that is in the home. 1. You can refinance the house to a new 15, 20, or 30 year mortgage (your choice). Most likely you would be able to take out 70-80% of the equity depending on the borrow's income and credit. Doing a refinance would cause you to have a mortgage payment every month for the next 15,20, or 30 years depending on what you did but you would be paying a low interest rate. This is most likely your best option if you plan on using the money to buy long term buy and hold properties. 2. You can get a HELOC on the property. This is a line of credit with the property as the collateral. Most banks will lend up to 80% of the value of the house. There will be some up front costs, appraisal, bank fee, survey etc, but when you are done you will have a "checking account" with 80% of the value that you can use. Normally banks like to see this revolving (being used and then paid back) within a year so this is probably not a good idea to get a buy and property with. The nice part about a HELOC is that if you don't use the money, you don't pay interest on it. If you use 10k you only pay interest on 10k for the number of days that the money is not in the checking account. It is ideal for flips and BRRRRR strategy 3. Last option is to sell the property. I don't think this is a good option.
For Options 1 and 2, you will have to go to a bank or local credit union. There will be paperwork and proof of income etc involved. You most likely will have to give tax records. If there are more than one person on the deed of the property, the combined income is normally used by the bank to determine if you make enough money to refi or get a HELOC. If one person does not work and the other makes good money then it would be the same as if both work and make half the money.
I currently am in the process of getting a HELOC on a property I own in Texas. I plan on using the HELOC for future flip projects. Let me know if you have any other questions. Also please note that Florida may have different rules than here in TX so keep that in mind.
