The neighborhood has seen a lot of revitalization in recent years, with an increasing demand for both residential and rental properties.

I own 4 two/three flats bought between 2013 and 2020 in Forest Park, Illinois, at low interest rates and prices in 200000's  They cash flow nicely and prices have increased a lot. 

Additionally, the house is 25 years old and could use cosmetic updates to increase rental appeal.

The shorter the prepayment term has an impact on increasing the rate.4.

We signed P&S agreements on 6 different properties totaling 20 units approximately 8 months ago and received a call today that the price we thought we were buying at has to-be increased on average 13% due to the increased cost of construction.

It’s just going to slowing increase with inflation.  

The shorter the prepayment term has an impact on increasing the rate.4.

I focused on adding modern luxury amenities to increase the property’s appeal to the high-end market.

Your taxes are none of the ex wife's business and this would seem to address your concerns.I would also put her on notice that future requests for financial discovery will be two-way and if a discrepancy is seen in the other direction you will seek support from her.

So what kind of property would it take for you to increase your cash flow by $2000 - $3000 a year.
