I can say in Detroit the wholesaler your talking to has most likely found that deal from 2-3 other wholesalers, they literally have to payout 2 - 3 other parties to get the deal and this is what the fees are high and the deal makes no sense.

@Nick HulmeMaking improvements to your primary to make it high quality enough to rent above market rents, rent it.

The last thing you want is to have a home run deal that theoretically should be a high-profit flip but is ruined because your contractor screws you over in some form or fashion (late deadlines, inaccurate scope of work, etc.). 

BiggerPockets also has a calculator to analyze deals, and I highly recommend you start this as soon as possible, even if you are not ready to buy.

When it comes to real estate, here's a general list of eligible assets and their depreciable lifespans that you should know: Residential Rental Property = 27.5 yearsThis includes any building or structure where 80% or more of its gross rental income is from residential units.That means:- Apartment buildings- Single-family rental homes- Duplexes, triplexes, and quadplexes- Mobile homes (used for residential rental)- Any kind of residential lodging facility where the primary purpose is long-term rentalCommercial Property = 39 yearsThis includes non-residential properties like:-Office buildings-Retail stores and shopping centers-Warehouses-Industrial complexes-Hotels and motels that do not qualify as residential rental propertyLand Improvements = 15 yearsThese include sidewalks, roads, fencing, some landscaping, and parking lots that are separate from the building.Personal Property = 5 or 7 yearsPersonal property used in a rental activity usually has a 5 or 7-year life.This includes most furniture, appliances, carpeting and various machinery.Qualified Improvement Property (QIP) = 15 yearsGenerally, this includes any improvements made to the interior of a non-residential building after the building was placed in service, excluding elevators, enlargements, and the internal structural framework.Computers and Related Peripheral Equipment = 5 yearsVehicles = 5 yearsNote that the land itself is not depreciable.

Most of these folks don't want to lose their voucher.Additional issue, when rent is too high, it slows down leasing. 

Lessons learned is not to buy a property with a high HOA.

90% is pretty high.

If prices are too high people will just go elsewhere.

If i were to purchase a 6 unit apartment for $280K, which fully occupied is roughly $5,050 a month.
