My wife and I own a portfolio of rental properties in and around Tacoma.

Im a 21 year old guy with a opportunity to seller finance a portfolio of 12 SFR.

Assuming you have a budget of $1M+ I would recommend that you could start by building your investment portfolio through flipping properties in the SoCal area because the appreciation and quality of construction is pretty good.  

plus if you don't charge interest IRS will hit U with imputed interest .. so you will pay tax on some of the income like it was interest income.IE you can do 3 and year and no more than 7 in your portfolio at anytime.. this is to allow mom and pop IRA investors to loan their own money I know this exists in Oregon..but if your in the business that's different. so if you have bought a park with 40 park owned and 10 rentals and you want to move those park owned to the tenants.. then yes your probably in the business.Eddie Speed has been working on a national committee to try to address seller carry back for US investors I don't know if he is making any head way. 

My thinking has shifted to index funds in a well constructed diversified portfolio, which I can do myself and save the fee.

Im staying the course but i dont own C class quad.Ran should think about cashing out a bit too......................hehehe.After all the rental expenses, my portfolio provide me $20k net monthly rental income, why should I sell it?

Excited about building my portfolio.

So far I’ve been working with a local portfolio lender who does 80%ltv and provides commitment letter in about two weeks.

Do you provide move in and move out reports How many pictures do you take of the property prior to tenant moves in and after the tenant moves outDo you get weekly reports when the property is vacant what prospective tenants are saying about your homeDo you provide monthly newsletters to your tenantsDo you hold investor education classes to help me become a better investorDo you have single point portfolio based management services?

If you want to grow your rental portfolio, you are swimming upstream holding assets that lose money every month/year.
