Madrid-  invest in properties foreign diplomats and military like to live, near good international schools, sights, their work, transit systems, available parking, etc.  

(Roeland Park is a high price point area, Which turns into Million dollar homes as you head South into Mission and Fairway.As you head NW, it turns into a C market area.

As mentioned areas like Harlandale and Mission San Jose are relatively safe and will produce good cashflow.I dont really like the Southwest quadrant of the city near Lackland AFB.

Goal: Build a passive income from rentals that will allow my husband, my daughter, and myself to live on mission for Jesus Christ.

I'm on a mission.

I had heard as you described about if in same vicinity, if the homes were significantly different life styles that you could get 2nd home loan.I live in inland north county San Diego (Poway) and wanted a 2nd home loan for a San Diego beach property (mission Beach).

Downtown area, last I heard, still had STR permits available (unlike Mission Beach). 

If no, you are wasting a lot of effort and I will tell you why.The more shady the marketing, the more you need to push your credibility scorre up.If you have a nmber 1 ranking website and a ton of reviews and you are all over facebook with thousands of lieks and comments and myou give to charity and people talk about you and Google suggests you when people seach for keywords... sure you have enough credibility.But put a bandit sign out and people have no idea who or what you are  they need to have a way to find you on their own when they try to do a bit of research about you.So now you spend all this effort cold calling and what not, and when you DO finally score and the person is somewhat interested or at least curious, and you can not provide a website with your mission statement, an about us, and info about you, guess what will happen.

Talk to him, share how you feel diplomatically and emphasize that you want to find a workable, fair solution for you both.

Our neighbors, a couple who harbored a narrow vision of neighborhood identity, opposed our mission to rent out our home.
