Also, added smart-deadbolt locks to each bedroom for extra security in house-hack situation.What was the outcome?

Cameras, security system, motion lights, cage lock on hvac, etc.They were stolen cause it was vacant and had a for sale sign.   

Looking ahead, once you secure a tenant, perhaps this is something that should be explored to make the next lease up easier.Also, @Caria Mitchell raised an interesting point in saying: We are experiencing a shortage of qualified applicants, I’ve noticed non-conventional applicants vs qualified applicants that don’t have a voucher or some form of subsidy. 

Very few allow any subordinate financing below their note but I do have ONE that allows 90% CLTV (they loan 75% and allow you to secure a 15% seller carryback as long as you come in with 10%). 

I had two lines of credit one unsecured for 5 million ( check book) and another for 10 million that we would secure them up with .. but you need time to do that bank required appraisal etc before we could tag the secured line and even at that they only lent 72% in these commercial loan structures..

Pro tip--make sure your exhaust fan in the bathroom is vented to the atmosphere--meaning out to the outside.....go out the roof or out the side of the unit or secured to an opening in a soffit vent grille off the house. 

Quote from @Kevin Rodriguez: After numerous unsuccessful attempts to secure a deal to cohost, I’ve decided to adopt a new strategy.

The state doesn’t have rent control laws, but landlords are prohibited from collecting more than one month’s rent for security deposits.

Random things like this.I can only imagine if they did allow you to add all the bedrooms, they would make you also add fire sprinkler system and a commercial fire alarm system like residential assisted living. 

Glad we're secured, but nothing in rei is passive.
