Can anybody provide a brief explanation on how the refi works for multiple properties?

From what you are mentioning I'm not sure a comp in another county would make must sense UNLESS the next county is geographically very close to the property.

I went through the same, I am an architect and real estate investor and got the license to support that.it seems you have experience and already some clients.I think EXP is the best option so far for that, beside many different income streams it provides.you can do both, residential and commercial from the beginning, and you are tide to MLS geographical locations, I will allow you to do both from the beginning.

If you keep looking at the appraisal, you will also see an explanation page stating why they used the sales comps as the primary valuation method.  

Remark: I sent them the Letters of Explanations right after I made the 10% deposits and they approved it.Is it ok for me to sue D.R.

The mitigations I use are to only invest with deal sponsors that I personally know and have seen their work, also diversify geographically and with different operators. 

Our plumber does give us a description of the blockage or issue and we screen this for tenant responsibility- ie superman was snaked out of the toilet, cat litter was dumped out of the now unusable garbage disposal (also interesting in non pet friendly properties) and we will pass that charge on to the tenant with appropriate explanation. 

Pick properties like that; example:  Great School Districts, geographical limitations (mountains, rivers, lakes), gated communities, etc. 

Many times the lender will require a letter of explanation to confirm its use/occupancy.

Thanks for the clear explanation Bill.
