In the Philadelphia market, most of the time a 130k house vs a 90k house can be the determination of a C- market vs C or C+ market.

The price per door you mentioned generally signals class C- or D units, which means the economic loss for the units diverges from pro forma assumptions DRASTICALLY in many cases.

Unless you find a duplex that needs work or is in a C or D area this is what you are going to have to settle for.

@Scott HensleyWhat market is the property located in and what type of asset (C or D)?

Basically, in the approval letter there will be provision that will say something like "there cannot be another transaction pending", or something else like "the property cannot be resold within 30 days".Simply put, to get around them, you may need to hold for several days, use separate title companies for the a to b and b to c, or try and contest the langauge.After you get an approval, you need to look for this language with your title company.

Also I wouldn’t recommend a C or D class to invest in without more experience.

Interested in multifamily in C+ or better neighborhoods to buy and hold.  

In my particular area, rent for a 3 bedroom SFH in a C or B- neighborhood has gone from ~$550/mo to ~950/mo in the span of a bit over a year.

Right now the problem Im coming up against is that I don't know if the neighborhoods Im looking in are any good, a.k.a. are they A,B,C or D neighborhoods.  

20 applicants and 20 evictions would be very rare, even in C or C- areas.
