It depends on your financial strength, the quality of the property, how many properties you own, etc.I like to start with one significant expense and three months of vacancy.

Also, I wanted to convey that the type of investor I describe should on;y accept a quality tenant well above what’s typically considered acceptable in the industry.  

The structure will depend on the down payment, quality of borrower, terms of note, your cash out of the note sale needs, and other factors. 

It's acceptable as an area though the flips I saw weren't great quality.  

You lose because there are many other suckers out there falling for the same line and sharing the same low-quality leads that don't translate into sales.Do the math.

So quality of tenant is irrelevant as accidents can happen.So most of your post demonstrates that you did not really think about it.  

McKinney is thriving, but so are other parts of North Texas, and a broader perspective could reveal other great opportunities.Here’s what I’ve observed managing a significant number of rentals in the area:Bedrooms and Layouts:3-bed, 2-bath homes consistently attract the largest pool of tenants and have the highest occupancy rates.4-bedroom homes have grown in demand, especially with the rise of remote work, as tenants look for extra space to use as a home office.Square footage is less critical than number of beds and baths.Supply and Demand:McKinney’s growth is driving demand, but the quality of the location matters greatly.

@Polat CaglayanI've never seen a formula but here is a general rule of thumb for multifamily:The class of an apartment refers to the quality of the building, which can be determined by a number of factors, including age, location, and condition: Class A: These are the highest quality apartments, typically built within the last 15 years.

The quality of answers to your are directly correlated to the quality of your questions asked.  

The exchange must also be for like kind and quality.
