Hi Ricky,Being in operation for 10 years with mid seven figures of assets and NNN leases,it would be wise to speak with your tax advisor regarding if the tax set up should be an LLC, an S-Corp  or a C-Corp.It would also be wise to speak with an asset protection attorney to find out if this is something that might be beneficial to you in that area.

An other advantage of paying with credit card may be that you will not have to send the provider a 1098 tax form (only an issue if the total yearly amount is over $800). 

That helps some...but your variable expenses also go up too - property insurance & taxes - so a lot of your rent increases go to offset rising variable expenses.I started at the age of 47 in 2018 and we bought properties fast and furious - 12 the first year, 10 the next, and 9 in 2021 and currently have 38 properties. 

Additionally, most servicers will provide the tax documents needed at end of year (1099-INT, 1098-INT) and can also issue notices of NSF, late payments and support delinquency /default.

How would this be accounted for for general accounting and taxes?  

@William TaylorMichigan has some of the most complicated property taxes in the USA.

Property taxes are 2% instead of 1% for landlords as a general rule (some districts may  be slightly higher). 

Taxes : Taxes have been a brewing crisis nationwide for sometime, Chicago is another prime example of a major municipality struggling under high debt load.

You can take any proceeds tax free and roll into a different investment. 

We're right next to CA but get the benefits of no state income tax, 4th lowest property taxes, much more friendly landlord/tenant laws, no serious weather, proximity to Lake Tahoe, stable job growth/population growth, etc.
