I am looking into purchasing a single family home ,and converting it into a duplex ,and a 2 car garage into a ADU what type of loan is recommended ?

Sounds like you are trying to do a Lease with Option to Purchase.This requires 3 separate documents:1) Lease2) Option Contract3) Purchase contract triggered when tenant enacts Option Contract.National statistics show that around 65% of Lease-Options fail.

What made you interested in investing in this type of deal?

Now officially my first rental property.What made you interested in investing in this type of deal?

That's hard to find because most investors are 'Type A'  Alphas.....

@Brandon Beaudoin@Josh St LaurentIt doesn't look to me like Josh did any more than type a question into Chat GPT and paste the result here.

From June until November I haven't received one payment, my court date was set on the Monday of Thanksgiving which the clerk couldn't give issue the court order document because she was swarmed with all the cases that week, the following week I received the court order and the writ.

However, I've had a very difficult time finding any insurance carriers that will provide this type of coverage. 

I'm familiar with the Texas lease and it still has holes that need to be filled with additional documents or solid policies and procedures.

The max Uncle Sam allows is 50k if you haven't taken a TSP loan in the last year.I've seen both good and bad experiences with this but at the end of the day it's no different from any other type of loan, you are just your own bank in a sense.The downside or risk is that you lose your job, your property isn't cash flowing, are unable to pay back the loan, and your retirement account suffers since the loan essentially turns into a withdrawal.The upside or best case is you have the loan for less than a year, your BRRRR pays off the loan, and you pay yourself interest 5% interest.The opportunity cost is if the stock market goes up 20% and you were only paying yourself 5% interest you'll miss out on the excess returns.
