Seeing 3 out of 4 should give you a good idea, and then during your physical inspection you can see the building. 

I'm thinking that Vegas makes sense as far as demand and a time share saves me maintenance fees and me having to physically be there. 

@Terry M Jordan Is the physical property straddling both parcels?

I want to put in an offer to tie the property up so I can do my homework (approve sellers books, records, leases, property management contracts, preliminary title report, underlying encumbrances, and physical inspection of the property.

@Jordan Moorhead: Just looking for turnkey investments so I can do OOS easily while working full-time on the side, as I would need someone to manage my investment property as I would not be physically there.

I look at it similar to a law of physics like gravity....It almost can't not happen.But I was wrong once......

You run comp analysis on similar homes, larger homes, smaller homes, adjusted for upgrades, lot size, condition, check the neighborhood for homes that sold the closest physically and adjust for how long ago they sold.

It really also depends on what property type you are using the HELOC on.For instance, credit unions will get quite aggressive on your primary residence and give you 85%-100% of the appraised value (appraised value can be physical or desktop appraisal).

Also has some good videos on financial modeling for real estate.Real Estate Finance and Investments - Brueggeman & Fisher - If you are looking for something physical that is a great resource for all things real estate investing, this is a great option.

I need to get some work done but I can’t physically be there.
