However, I’ve found that these strategies don’t seem to align with the current real estate market in my country, Pakistan, particularly in Karachi.Here’s an example:A typical 120-square-yard house with 4 bedrooms and 4 bathrooms costs around 106,000k ($270-$300 Rent per month).

Typically in Kihei the 1 beds offer a better cash on cash return but if you need a 2 bed for personal use that would make sense . 

In a seller's market, home prices typically increase due to limited inventory, while in a buyer’s market, prices tend to be more negotiable.

Is it one investor per deal, then they would act as a private lender and that typically includes a note, deed of trust, loan agreement, personal guarantee, assignment of rents and a few other docs.

@Frank Newsome typically there is not a good separation on areas for Section 8. 

You're talking about the west side of Akron, which is a solid rental area and can range from C- to B; but most houses were built long before 2000 - typically in the post war boom 1940s-60s. 

Is that what you typically recommend for an investment property, or would there be any flexibility depending on the city or type of property?

And these tenants, typically, were rougher on the property during their tenancy, so those more frequent turnovers cost more each time.  

Lis pendens are not typical in trustee states because trustee states use the power of sale clause to foreclose, and don't use the courts.

Typically there are only a few available at a time.
