But the other thing: depending on the project, you may need to spend a ton of time physically meeting and working with contractors.  

How about # of units, borough(s), proximity to Manhattan (and/or nearest subway station)?

I'm not certain how USAF is, however, but my first question would be about where your Mk1SU is physically at.

But I wanted to know how many of you buy properties without physically seeing or visiting the property.

It looks like we are pretty close in proximity.

We're  looking closer proximity to boise state ( we're  thinking the vacancy might be less but if you have other suggestions I'm all ears, any thoughts on the bench area or other good areas to look for multifamily?

Hey,already learned for several months and analyzed some real deals.Still in my learning phase, after reading a lot logs and talked with different investors/brokers,just would like to discuss/clarify some important points for underwriting apartment buildings (> 6 units, income properties).First way to underwriting apartment building is based on the actual/verified seller financial datas (income/expense) and market prevailing cap rates to get reasonable market value, then based on the physical (rehab costs) condition to get the offer price.Another way is my prefer and most value-based methodology.First of all, based on the market research to come to your own expense (property manger expense, insurances,taxes,cap expenditure sand utilities) and based on the market condition to come at rents or other income numbers, to get your own NOI and cash flow.Then base on the value-play plan (financial terms and holding period) and (most importantly) IRR target for the property.Use the expected cash flow,IRR,holding period and expected exit price to get the offer price.Just wonder which way is better from the value-add investing perspective?

The reality is that so many people live so packed in close proximity to public water sources this becomes a public health issue.  

So eight months later when you apply for your next mortgage, things like paystubs, tax returns, bank statements, etc, need to substantiate your physical residence in the property in question. 

But one thing all landlords know is that you can't physically force someone to pay on time.
