Would love to hear your thoughts on whether pursuing this adjustment makes sense or if I should reconsider.For reference, I’ve included the following assumptions in my calculations:5% for maintenance3.5% for vacancy10% for capital expenditures and management feesThanks! 

My assumption is that the shortest amount they'll want to see is the last three months (90 days).

They are all disparaging the course based on superficial knowledge and assumptions. 

Probably 8%+ mortgage interest at 40% down to make a safe assumption.

@Isaac Terry Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

In my analysis, I utilized a 40% assumption as a baseline, though I acknowledge that this may underestimate expenses for a park with the characteristics you’ve described.

If the proforma has the rent roll at $1400 a month, there is a discrepancy that could lead you into a bad assumption on your business plan.Also one caveat, be aware of physical delineations around the area like bridges or railroad tracks or a canal. 

Borrowing costs are nearing their highest point in decades and the municipal and state debt crises do not get nearly the attention of the federal government or deserve.Environmental Impacts : My assumption is that the entire toxic debris removal process will have to be managed by the Army Corp of Engineers X FEMA and other governmental agencies.

@Mattin Hosh first, most cities in Metro Detroit have some type of rental property inspection every 2-3 years.It's not really a big deal 99% of the time - especially for owners who are NOT slumlords:)Also, a quick Google search will show that several states/cities are passing/considering similar legislation.One of the biggest mistakes we see newer investors making is NOT properly understanding Neighborhood/Property/Tenant Classes and naively assuming that any rental they buy will deliver Class A results.Read our copy & paste thoughts below and DM us if you'd like to dicuss more about the Detroit market:)-------------------------------------------------------------------------------------------------------Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?
