I know, I owned a gym for 6 years and got out before business was effected because it was becoming a grind.

If as I mentioned, we used 12% instead of 10% for PM fee, this would in effect add $141/month in "tenant replacement costs", if the tenant churns in 18 months we've "escrowed" $2,538 in total for the replacement - roughly 3x the actual cost.  

whats everyones thoughts on the convid-19 and how will it effect the market in upcoming months?

I have no idea how this is going to effect selling the property.  

I would say the 1% rule is not the most effective way of looking at larger (10+ unit) multifamily properties, but as others mentioned it depends on the area and type of deal.

The “key” elements of the transaction are explored first and usually, the most intensively.The buyer should provide the seller a comprehensive disclosure statement and include a term in the purchase agreement that obligates the seller to return the document within 5 days of acceptance.Professionals are hired to complete Phase 1, 2 & 3 reports that identify potential or existing environmental contamination and all other elements of elements that are difficult for the buyer to effectively evaluate.Financial Checklist3 years profit & loss statementsRent roll with space number, name of resident, move-in date, renter or owner occupied, number of occupants, monthly rent, additional charges, current balance due and any relevant notes about the residentList of capital expenditures for the last 3 years3 years of tax returns12 months of bank statementsCurrent accounts receivable statementList of park owned home including copies of “rent to own” or sales contractsCopy of all current insurance policies, binders and premiumsSpreadsheet detailing who pays all utilities including water, sewer, gas, electric, trash, cable, etc…For all utilities and charge backs, formulas, calculations and meter readings for the past 12 months3 years of utility billsProperty tax bills for the last 2-3 yearsCurrent staffing list including position, wages, job descriptionsCopies of any contracts that will transfer to buyer including laundry, trash, phone, equipment, etc…Dates and amounts of the last 3 rent increasesSigned rules and leases for each residentNames and contact information of professional service providers including lawyers, accountants, engineers, insurance brokers, inspectors, appraisers, realtors/brokers, etc…Physical ChecklistSpreadsheet for utilities that details age, composition, capacity, physical locations, etc…Any drawings or maps of the park and infrastructure including lot sizesSewer plant or septic system repair and maintenance recordsWater well tests and compliance recordsDisclosure from seller of current or recent problems with infrastructure including buildings, water, sewer/septic, gas, electric, etc…Names and contact information of contractors including plumbers, tree surgeons, electricians, gas inspectors, septic companies, roto-rooter services, etc…Locale ChecklistProfile local housing market:“Stick-built” – current foreclosure rate, months of available inventory, median home price, average rent per month, vacancy rateApartments – average rent per month, vacancy rate, prevalence of move-in specials…MHPs Comps – average monthly charges (rent, utilities, etc…), vacancy rate, # of homes for sale, etc…Profile local economy including population, major employers, unemployment rate and trendsCopies of city, county and state permits, licenses or certificates of occupancyCheck zoning for recent or pending changes to target property and adjacent parcelsCheck for known environmental issues with target property, adjacent parcels or in the communityCheck for major development or construction projects in the communityReview existing surveys or environmental reportsConsider geographic factors including elevation, annual snow fall, rain fall, proximity to bodies of water, etc…Disclosure from seller of current or recent lawsuits, regulatory or compliance issues, fines, fees, etc…

As an investor, we tend to look for modest improvements that are cost-effective long term.
