For instance with Fannie and Freddie (at least in the past) as the number of houses you own goes up, the amount of cash reserves you need also goes up.

For instance, how would you fare financially if you discovered tree roots had compromised the sewer line (~$3500 repair) and soon after your tenants stopped paying rent and by the time you evicted them and got new tenants in you endured four months of no rent payments coming in?  

In Montgomery County for instance the county produced a lease that they highly "suggest" you use.  

We chose these locations due to convenience for self management and house hacking (local or where we have extensive networks) not because they were necessarily the most lucrative markets.

If you do have extensive experience then you could use the credit as a DP possibly.

In the past I may consider in the first instance starting out but hard pass now.  

@Omar Torres  That is a very large and extensive question. 

I didnt know that it included PM, for instance.

Maybe we can blame it on his extensive DRUG ABUSE.

For instance, you and Jon (thank you both) have shared links to two companies that regularly produce information-packed reports, and these reports provide some level of analysis for the company's purposes.
