As with all things financial, there are some rules associated with how you invest in these accounts, and who you invest with.

I don't know all the facts but if you are looking for financial growth and a stronger return on investment, I would use the cash on hand to purchase another investment (or more).

I believe the changes will only satisfy your personal not financial goals.If I were to change anything I would either run the front stairs straight up to the 2nd level as opposed to a platform and branch stairs to the sides.

Great financial advice as well.

There are lenders that will base their lending decisions specifically off the rents received, not off your entire financial situation.

My husband and I are looking for a partner (financier) who can help us structure a deal to buy our duplex from our landlord. 

Account Closed I'd say with those 2 books you are ready to move onto next steps which is: networking with investors in  your area, find an investory friendly agent, and start getting your financials into order. 

The kind of thing that doesn't make or break your project financials - ie perhaps the jurisdiction doesn't have a great chance of 'making' you do it, so you can take it on more from a 'bring upside value' to your rents, etc.... and you get some 'soft' experience working through jacking something, pouring 1x new footer for a corner post, etc.  

Learning all of that ahead of time will save you a bazillion headaches and potential financial strain later!

What specifically do you plan to do to force appreciation, and therefore possibly increase rents, and therefore property value and overall financial performance?
