You're selling for $45K so your gain will be around $17600 (you may have some costs of closing that lower that figure).In order to do a 1031 you must purchase at least as much as you sell or pay tax on the difference.  

Of course that's contingent upon their level of risk-aversion.

It's where you rent out a portion of your primary residential home to drive the cost of your own living expenses down.Myself I have a 3b/2b trip level home and I rent out a bedroom for 450/m and slowly working on getting the other room into a STR.

Your interest rate will be lower, but you'll have to pay a 4.75% fee that will be added to your mortgage. 

If they are paying high rent per sq ft then you need to know they are making high sales otherwise they will want to close that store, sub-lease to someone else, or try and renegotiate the rent lower.If they try lower rent and per lease they do not show financials you could demand personal and business financials to consider the reduction.

Open it up and run fans and dehumidifiers for about 8-12 weeks and you will start to get to the moisture content levels that allow you to start replacing insulation and closing walls.  

Should I lower them? 

I'm not sure whether to lower price or install a washer dryer or take other action to get it rented. 

C = lower middle class housing, more multi-family mixed in but decent places, some crime but low-level stuff nothing dangerous or violent.

I want to attract a decent renter with a decent home that will work with me to fix up the property and bring it to the same level as the rest of the neighborhood.Does anyone have a list of standards for a mobile home community?
