I have never performed a brrrr on a mobile home, but my most successful BRRRRs are where rehabs add the most value.  

No experience with non performing notes.My idea is to buy these notes with the primary goal of accessing the property through foreclosure, knowing that there are several other possible outcomes.

Defaults and Remedies A default exists under this note if (1) Borrower defaults in the payment of this note or in the performance of any obligation in any instrument securing or collateral to this note; (2) (a) Borrower or (b) any other person liable on any part of this note (an "Other Obligated Party") fails to timely pay or perform any obligation or covenant in any written agreement between Lender and Borrower or any Other Obligated Party other than as described in (1) above; (3) any representation in this note or in any other written agreement between Lender and Borrower or any Other Obligated Party is materially false when made; (4) a receiver is appointed for Borrower or an Other Obligated Party or any property on which a lien or security interest is created as security (the "Collateral Security") for any part of this note; (5) any Collateral Security is assigned for the benefit of creditors; (6) a bankruptcy or insolvency proceeding is commenced by Borrower, a partnership of which Borrower is a general partner, or an Other Obligated Party; (7) (a) a bankruptcy or insolvency proceeding is commenced against Borrower, a partnership of which Borrower is a general partner, or an Other Obligated Party and (b) the proceeding continues without dismissal for sixty days, the party against whom the proceeding is commenced admits the material allegations of the petition against it, or an order for relief is entered; (8) Borrower, a partnership of which Borrower is a general partner, or an Other Obligated Party is terminated, begins to wind up its affairs, or is authorized to terminate or wind up its affairs by its governing body or persons, or any event occurs or condition exists that permits the termination or winding up of the affairs of Borrower, a partnership of which Borrower is a general partner, or an Other Obligated Party; or (9) any Collateral Security is impaired by loss, theft, damage, levy and execution, issuance of an official writ or order of seizure, or destruction, unless it is promptly replaced with collateral security of like kind and quality or restored to its former condition.

Quote from @Jonathan Greene: Never sell a high-performing property with no cap ex and low maintenance to buy another rental.

We always perform a clean and inspection, with photos, before move-ins.

A cost segregation study was performed on this auto repair shop in Nevada with a depreciable cost basis of $1,250,000.

@Eugene Lubman Selling the property to your parents allows them to generate passive income while enabling you to perform a 1031 exchange to defer capital gains taxes.

Does the original poster have someone who can do that like some of the people he mentioned did?

Purchase price: $125,000 Cash invested: $25,000 Sale price: $230,000 Bought the property about 4 years ago, originally it was a 2-family rental.

While some leases say they will remove all evidence the sign was there and restore to original condition, I doubt that happens in bankruptcy for example.
