Is it worth paying their annual subscription fees and do their 30-day rent guarantee mean anything if they aren't refunding the payment?

Don't pay LLPAs and take the high interest rate?

Determine what price you can pay for the property.

There is no set time for the county to foreclose on the property via a tax sale, according to this article purchasers of the tax lien certificate have to wait 5 years, as the owner has a redemption period after the tax sale, so you could be waiting a while, and if I'm not mistaken, you have to pay the taxes each year until the 5 year period is over, then you have to file for a deed or file a lawsuit to quiet title.https://smartasset.com/mortgage/how-to-buy-tax-liens-in-cali...Hope this helps,Dustin

@Matthew Crivelli  HUD Section 8 does not pay above market rents. 

It'll be important to know how much taxes you're gonna be paying when you sell it.

I have been using Rentredi, but allowing them to pay through cash app/venmo. 

As a buyer, I like 20% down and to pay 6% interest only for at least 5 years. 

Applicants pay a one-time application fee, which is valid for 30 days, allowing them to apply to multiple properties within that period using the same fee.

I'm looking more for an overarching portfolio spreadsheet to track asset performance over the lifetime of holding the asset.If you have the property manager paying the mortgages, taxes, insurances, doing all the accounting, etc why not just ask them to generate whatever report you want?
