I know what seller financing would involve in regards to me (the buyer) having to pay a interest rate set by the seller and the monthly payments also set by seller.But what are the benefits of seller financing a property?

BUT………when asked a DIRECT question, it behooves the person attempting to build trust to provide a truthful direct answer, not insult the person asking the question and not by saying I don’t have to answer that, and not by stating the same unclear statement that was the Catalyst for the question.  

At closing, the buyer and their lender determine whether the credit will reduce down payment, closing costs, or as a credit.5.

With $250k in cash, you can easily do down payments on 5-6 rental properties here. 

You will want to consult with a lawyer.In regards to your last two questions here's some background on what makes a contract valid and enforceable:Offer: A promise to do or not do something within a certain time period Acceptance: A clear and direct statement that all terms and responsibilities are accepted Consideration: A legal and adequate inducement given in exchange for the promise Capacity: The parties to the contract must have the legal capacity and competency to contract Awareness: A party must be aware of the contract Legality: The contract must be legal in the jurisdiction it will be operating in***Not legal advice*** Steps I would take: -Review contract in detail to understand each counterparties responsibilities (if you are not aware)- Email a copy of the lease to each of the tenants listed on the lease and reiterate lease expectations for termination notice, rent payment etc. - If the lease was signed via Docusign (other esign may have same ability) - you can go to the envelope, go to history and view the IP addresses for each action taken.

Quote from @Charles Fay: Hello all, first time posting and wanted to ask for your advice.currently in the military awaiting a 9-12 deployment within the next 6 months.I will have ~150k savings after deployment, 85k before, with no debt, payments or anything other than basic bills, 750+ credit.

In this manual (which I assume could be modified to provide to tenants) I include all the financing information (which you would not include for tenants) bank accounts, mortgage accounts, payment information, and mortgage payoff), a list of the contractors, what each contractor does, a list of upcoming planned or necessary repairs, and a copy of all leases associated with the property.

His greatest value is me trusting him. 

You are correct, local banks would go in and sit with them and go through rates and financing and understanding the payment.

A follow up question I now have would be do you think its smarter to completely pay off the first property before buying a new property or to keep going out and buying new properties once i have enough saved up for the down payment along with extra fees?
