I have 2 properties i'm planning to purchase and wonder how is the crime and rental market in there. your response is much appreciated

The only two ways to rectify this are (1) purchase the property far below market price or (2) significantly increase the property net income usually through some method of “repositioning”. 

DOM nationwide isn't really terribly useful; in extreme situations we will already know the national economic situation.

Curious thoughts on the following scenario.Current SFR with $51k loan at 8.125%, just purchased with around 10% built-in equity on the property, $250 monthly cashflow (post expenses).

I guess the idea is to use the equity from one property to purchase the second property, and so on.

Unless it is a new build, and it comes with purchase warranties are an extra cost and may or may not even be executed when needed depending on the circumstances. 

Id like to put a HELOC on it or redelop it after a few years, the whole points of purchase is this is a booming downtown area lot of development rights etc, dont want to be in a financial structure that banks will frown upon. 

It seems that if you can find a good deal on the purchase price, are willing to do cosmetic updates (floors, painting, maybe a kitchen) you can get that 100-200/month cash flow.  

My last purchase (built 1900) has no closets.

Purchase price: $15,000 Cash invested: $25,000 Sub to deal - paid the seller and wholesaler $15,000 + $7500 closing costs to assume $84,000 mortgage with a monthly PITI of $575.
