My terms are identical to yours as far as the 1-year lease with 3 options to renew (for them), 3% yearly rent increase, etc.

PS is revolutionary because of how it has simplified access to all of the various data points investors need to make a decision and because of this its extremely popular.You do not want to be using a popular lead source to increase deals because everyones chasing the same deals.And nothing will change with there data because there business model forces them to have to buy and license the data they get which means waiting for the county/databroker to send it to them which guarantees anyone using PS data will be behind the counties, only getting a fraction of the leads and getting those late leads the same time as everyone else.How do you get access to the leads first.

Or is it calculated daily and the base rent increases after 10 days when the late fee hits the account?

I've had to override Christmas 2025 to make it higher because PriceLabs has it too low...but if I increase my base rate, the other dates are off...this may fix itself over time as PriceLabs learns my occupancy and rates, not sure).  

Quote from @Basit Siddiqi: I personally would not buy real estate with a retirement account.There are just too many headaches that are not worth the potential increased return.Some headaches when it comes to investing in real estate with a retirement account1) LTV values are less and harder to find lenders.2) Potential to sell or partially distibute the property if you have to do a RMD(Required Minimum Distribution)3) If you run out of cash and have to make a major repair, you may be out of luck and have to sell.4) Having to potentially worry about UBTI(Unrelated Business Taxable Income)I would personally invest in stocks/bonds/notes with a retirement account.I buy deals with cash and use a ROTH SDIRA so there are no RMD's.I buy at huge discounts to retail.

.- long term: there is a shortage of properties in almost all cities and in some cases and that has contributed to an increase of rents and prices in double digits in some cases. i.e Mafra 10% rent increases last year and Setubal +15% price increase.

They become renters, MASS increase of renters.

My estimation was with leverage I could do about 7 homes a year and each year after it would increase. 

Anywhere that one can buy properties for under $100k is very unlikely to have the rent increases that you will need over time to create positive cashflow, or the price appreciation that you will need to make this a profitable endeavor.

Higher assets or cash in the bank increases what is called you compensating factors which banks/lenders use to qualify.
