In the chart of accounts, create the new fixed asset type accounts for what you are buying, and an accumulated depreciation account for each. Also create an expense account called depreciation expense.
Create a loan liability account named for yourself.
Deposit the total amount being borrowed to the cash account and use the loan liability account as the source account for the deposit
Then use the cash account to buy the fixed assets, use the appropriate fixed asset account for each purchase and teh cost of the purchase
When tax time comes around, journal entries
debit depreciation expense and credit accumulated depreciation for each fixed asset.
Opinion: the loan still exists, and has to be paid back to the person loaning the money, there is no way around that. That is also true for past loans to yourself.
