Good news for you, NB has a fairly balanced Landlord - Tenant regulatory environment; particularly in comparison to jurisdictions such as Nova Scotia, Québec or Ontario.

But these are the kinds of regulatory concerns that have to inform your strategic thinking.

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…

Regulatory differences in who can invest and how drives much of the primary differences. 

It can also be slow to get a tenant in using section 8 programs, since there are more regulatory hurdles to jump through.Other than that you'll find that the payer (mostly NOT the tenant themselves depending on the voucher value) pays on time, every time, no matter what (so far). 

Much of what he has written is factual or makes logical sense, while most others shared what works for them, without considering the big picture.So, let's try to sum up your options:1) DIY Tenant PlacementPROS: Save moneyExperts know legal & regulation issuesYou have final decision, but can't blame anyone but yourselfCONS:Your lack of tenant screening knowledgeCostLack of legal & regulation knowledge2) Hire a Real Estate AgentPROS:Local expertsYou can still DIY manageCONS:They often lack detailed screening knowledgeThey may not know all PM regulationsCost3) Hire a PMPROS:Should have thorough tenant screening process better than all aboveShould know all legal & regulatory issuesShould give limited tenant-performance guaranteeCONS:CostYou usually don't have inputCan you trust them?

There's quite a bit of regulatory hoopla. 

Last I checked, they still had an income and net worth test, but even lower middle class people could qualify.That being said and to Chris's point, regulatory filings and operating costs on such a venture can add up. 

This is going to be a really state specific question, because each state's laws on short term tenancy are going to be different, and the requirements for transaction volume without a license are going to be different.This might be the point where you should call an attorney in California to help you set up the company, as they will discover most of the regulatory compliance issues in the initial research for putting the business together. 

I am similarly convinced this has nothing to do with good investment practices, but rather with making sure they don't put themselves in the crosshairs of building regulatory organizations for promoting shoddy DIYing.
