For example, for property taxes, you can search Google for what the state taxes are on a primary/secondary property.

Hi thereI am new to investing, looking at a SFH for my 1st rental property and trying to understand the tax benefits that are often spoken of on the podcasts. 

Supreme Court's Wayfair decision, Pennsylvania may require collection and remittance of taxes from businesses that have a substantial economic nexus in Pennsylvania"But from this site, it looks LLC needs to file Penn state tax no matter its size:https://www.revenue.pa.gov/TaxTypes/Partnerships-S-Corps-LLCs/Pages/default.aspx#:~:text=Limited%20Liability%20Companies,pay%20corporate%20net%20income%20tax."

Do they have a tax return coming that they could use to catch up? 

For other variables such as tax rates and heating costs, I find it easier to get a good evaluation.

I get the tax benefits on top of that (this is a big one for me), some small principal paydown, small monthly cashflow etc. 

Hi, so I won a tax deed at an auction for a vacant lot but I am trying to determine if there are a bunch of leins on it.

Most Jumbo lenders use IRS returns net number so be careful filing your 2023 tax return in not making the expenses total greater than 25% of income which will generally be the hit on gross rents. 

So you will need to know the rules where you work, as well as know the sales tax requirements, for where you are working.

I think this makes everything cleaner for taxes, documenting historic rental payments, and legal issues that may arise due to the barter, etc.
