I have a few certificates on vacant/abandoned houses and as soon as I start maintaining the grass I start getting calls requesting to buy the property.

I ended up going back to school and completed a data science certificate and I nailed a great clinical data job.

Is there any creative way I could obtain the property and take out a hard money loan myself to have the work done and then resell the property myself?

My practice is mostly in the area of RE (State Board of Legal Specialization is the only authority that can permit a lawyer to say they "specialize" in an area of law, which requires fees, exams, and a "pretty pretty please".)Attorney fees are based on several factors that have been thoroughly litigated:(1) the time and labor required, the novelty and difficulty of the questions involved, and the skill required to perform the legal service properly; (2) the likelihood that the acceptance of the particular employment will preclude other employment by the lawyer; (3) the fee customarily charged in the locality for similar legal services; (4) the amount involved and the results obtained; (5) the time limitations imposed by the client or by the circumstances; (6) the nature and length of the professional relationship with the client; (7) the experience, reputation, and ability of the lawyer or lawyers performing the services; and (8) whether the fee is fixed or contingent on results obtained or uncertainty of collection before the legal services have been rendered.Like other professionals that are free to set a market rate, we gauge the highest wage that the market will bear. 

Seller financing would be where you'd be obtaining the property and going on title and the seller would become the mortgage/lien holder. 

Or is there some other way that I can obtain financing on a home/repairs that costs more than the amount of equity I have.

@David RushtonIMO most people entering the real property arena fail because they do not obtain a solid educational foundation and knowledge about real estate.

Not always, but 99% of the time and you will find more than a few obstacles to obtaining those funds if you can't demonstrate some experience in this area of investing.

Do I have to get a job just to obtain a loan for a property that can more than pay for itself?
