There are a lot of people that have already addressed your specific questions on BP so you might want to read their posts. 

My idea was to find a complete list of all of the addresses in these neighborhoods, and then find out which houses have large equity %'s as to target them. 

And I addressed earlier in this post you can have more than 4 mortgages. 

To replace a hard money loan, you have to compute how many points you are paying on the new loan, LTV, the closing costs and a myriad of other things.PM me with the address if you have it on the market and I will check to see if any of my San Antonio buyers are a good a fit.Ken

However, I would like the option to raise it in a few months after I have addressed some of the repairs that need made.Is there any reason or need to ask the tenant sign a new month-to-month lease with me at this point?  

Many title companies even have curative departments dedicated only to addressing issues on closings they have done. 

They often rule out a 1031 Exchange because they are tired of dealing with property management issues, but they might be interested in a 1031 Exchange if they consider investment options that do not involve property management headaches, such as:Net Lease Properties (often referred to as triple net leases)Delaware Statutory Trusts (DSTs)Tenant-In-Common Investment Properties (TICs) @Leslie Pappas can address the DSTs.

They have 2 different addresses (1900 and 1902 Main St) and 2 stand alone buildings one the same property lot.  

I've done so because I live with and take care of my father, but my "permanent address" is the condo.This condo is owned free and clear (not %100 mine), and would work better as a long term rental.  

I am also interested if you would be willing to send me some numbers or an address so I can take a look at it!
