My dad once said if it isn't dangerous it wouldn't be fun. 

With exception of the accountant, these individuals did not go to college with these careers in mind.She can use my properties to suppliment her income without a lot of work and, in my opinion, have a lot of fun doing it.

Needless to say this is no fun.

In your case looking to larger assets where you can effeciently cost segregate to gather bonus depreciation would be a smart move.Appreciation - Where in the country is the asset class you like growing or going to be growingAmortization of the loan - What sector or even region if you look locally for funding, is going to offer the most favorable lending so that less goes to interest expense and more to pay down of principle.Have fun with a spread sheet comparing these 4 returns from your investment with the type and location of assets you find attractive. 

Digitize physical receipts for easy storage and use a consistent naming convention for easy sorting - 2024.03.25 Home Depot.Maintain proper records, such as contracts, settlement statements, and promissory notes.Additionally, you can track income and expenses consistently using software or spreadsheets.As you scale, if bookkeeping isn't fun, consider hiring a bookkeeper for a couple hundred bucks per month.
