It's worth going to the seminar to try and pickup on the free information however it's ultimately a high pressure sales scheme where you will be forced to make a choice to invest a large sum of money with a lot of unknowns.

I've dedicated many of his songs to my wife when we were younglings dating.Lol.Anyways, Let's make some assumptions here before we tackle this multiple choice question you have posed.

Occasionally a tenant has done some significant damage, but so far nothing that was insurmountable.We put an emphasis on offering good rental units (B & C), maintaining them well, establishing keen rental criteria, thorough tenant screening, a strong rental agreement, clearly discussing every aspect of the rental agreement with the tenant before we hand over the keys, establishing and maintaining good relationships with tenants, good relationships with neighbors who will alert us as needed, a good relationship with local law enforcement, regular property inspections, swift follow-up to rental agreement violations, sufficient insurance and a sufficient reserve fund.We stand behind our mission statement:   "We strive to provide safe, clean, affordable, comfortable, and quiet housing for responsible renters in the neighborhoods of West Vancouver."

Raising the rent is the wise choice, I would personally go to $800 if that is what the going rate is, however, you may choose to go to $750 to match the other unit (if comparable quality).

The one clause I do add to my purchase contract is "buyer has sufficient funds to close all cash, but reserves the right to close with hard money loan assuming no cost to seller and no delay in close."

@Tara Piantanida-Kelly   no Warzones or Ghettos in Wyoming or Oregon  good choices for out of state investing. at least for piece of mind :)

If so your two best choices would be to 1) Do a refi and pull cash out. 2) Get a line of credit. 

If they have a unique rent amount, I give them a choice of paying online via www.erentpayment.com, or depositing it directly into my business account at the bank.

I have residential loans on properties 1-3 and commercial on properties 4-11I do not like commercial financing because of the 5 year balloon (never know what rates will be in 5 years) but I really had no choice.  

The county I live in gives a choice of finding a home, apartment, or using a voucher for your current residence.
