You can say houses are much more expensive today!

When you say as long as its not directly in flight path, meaning - when plane flies over the house?

However, they approach financial health from different angles.The 50% Rule is a quick estimate that suggests operating expenses (excluding mortgage principal and interest) will roughly equal 50% of the property's gross income.The DSCR is a more precise calculation (Net Operating Income / Total Debt Service) that determines if a property generates enough income to cover its debt obligations.Deal example:- Class C middle class neighborhood- 4bd / 2ba single family house- ARV: 190k- Purchase: 105k- Rehab: 35k- Market rent: $1,400-1,525- Section 8: $1,475- Property manager: 10%- Taxes: 125 month- Insurance $1250 yr- HOA: $55 month- purchased and rehabbed with all cash.

If the house is older than 15 years old and an ADU is added, it can become rent controlled.

I have some in-house laborers for any large projects but sometimes value add can even be raising rents to market or finding an off market gem. 

And IMHO, the prices are dropping big time (on avg. 10K/month...houses that were above 300K a year ago are not selling at 250K now) and the available rentals saturation is worse than I seen during summer season (with rents dropping from 1$-1.08/sqft to 0.8$/sqft and very little contacts and applications...just go in Zillow and look how many rentals are on the market now in Kyle, New Braunfels or Converse). 

on a 100 year old house that rents for $1000 a month that's about to need a new everything - that is spectacularly deficient.  

But I do have some family in Canada that have told me there has been some tax increases to the STR owners to try combat housing issues.

Quote from @Stacy Banks: Hello I wanted to know what does it cost to do foundation & framing for a 1,500sq ft house being built in Lehigh Acres Florida.  

I recently found a house in Dallas (listed on Zillow for 120 days) that is 100% owned by the seller, and they're open to seller financing.
