They should be able to give you an idea of current value/ARV. 

I am currently looking at a few locations/properties though Zillow, redfin etc. to get an idea of the rent/cash flow potential in the surrounding areas.

I know the neighborhood well, especially in terms of pricing, and I had some ideas about modifying this house.

thx experts If you have the CAPITAL, it’s never a bad idea to buy the scale.

Keep your mind open to new ideas, persevere, and utilise the plethora of information and tools that BiggerPockets and similar platforms have to offer.

We use the RHAWA lease agreement, if you are not a member of that organization or WLA, I would recommend you sign up.In the RHAWA lease agreement (not Seattle specific), it states that security deposit can be used all purposes including unpaid rent, damage, cleaning, late payment, utilities, keys and other charges.It is never a bad idea to pay for an hour of an attorney's time to go over any of these concerns and then you can be confident you are following the law.

I am not saying that it is a bad idea or not worth it.It appears that you are doing just fine.

I have very little knowledge on it but the idea intrigues me as a way to obtain more property over the coming years. 

Since I entered 10% into VRBO rather than it prompting me, I have no idea if they are going to send what percentage to whom.
